Ernest Rutherford: Father of Nuclear Physics

Ernest Rutherford was one of the most important scientists in the history of man. Actually, he is sometimes regarded as the "Father of Nuclear Physics" since his outstanding works have dominated the understanding of atoms, which are minute particles that constitute everything around us. This paper addresses a number of pertinent issues relating to the life and achievement of Ernest Rutherford: the atomic model, atomic theory, important discovery, and even interesting facts about the proton.

Rutherford was born on August 30, 1871, in a small town called Brightwater in New Zealand. He was the fourth of twelve children in his family. His parents were hardworking and wanted all their children to study hard. Young Ernest was talented and loved learning, most of all science.

Ernest Rutherford was one of those kids who would always like to know how everything works. He would take anything apart just to have a glimpse of what it contained inside! His curiosity did not die down with time and led him to receive formal education in physics and chemistry at college. Ernest Rutherford did his education in New Zealand, and after that, he moved to England and went to the famous University of Cambridge for higher studies.

Ernest Rutherford's Discovery: The Nucleus

Probably the best-known achievement of Ernest Rutherford involves the discovery of the nucleus, that is, the very center of an atom. Most everyone believed atoms were nothing but solid balls of matter before his time. Ernest Rutherford was able to show, by experiment, that this was incorrect.

The famous experiment by Ernest Rutherford, commonly called an experiment with gold foil, was held in 1909. He bombarded a foil of gold with tiny particles known as alpha particles. The prediction was that the particles would simply go ahead and through the foil, but there was more to it than meets the eye. Though most of them actually passed on through, some then bounced back, seemingly having hit something solid.

That result cooked up a huge discovery for Ernest Rutherford. Indeed, he discovered that the whole concept of an atom being a solid ball was false, and there really existed a small, dense center within the atom: this is known as the nucleus, where most of the mass of an atom is focused. That was very important in understanding the basis of atomic structure; it became the basis of modern nuclear physics.

Ernest Rutherford Atomic Model

The discovery of the nucleus by Ernest Rutherford led to the formulation of the current model of the atom, known as the Rutherford atomic model, or by many others as the Ernest Rutherford model of the atom. At that time, atoms were thought of as a type of "plum pudding," wherein the electrons were scattered inside a positively charged "pudding." The Ernest Rutherford model of the atom totally changed this idea. His theory suggested that an atom consisted mostly of the space between the nucleus and the orbiting electrons. There would be a small, dense nucleus at the center. These small negatively charged particles, electrons, move somewhat as planets do with regard to the sun. This model represents a huge step in the line of progress to the modern understanding of the atom and replaced the old "plum pudding" model.

The atomic model of Ernest Rutherford helped scientists understand the structure of atoms and further their understanding of how atoms behave. This was an important mark in the field of both physics and chemistry.

Ernest Rutherford Atomic Theory

The theory developed by Ernest Rutherford in the atomic theory can be comprehended from his discovery about the nucleus of atoms and his atomic model. The theory described that atoms consist of a small nucleus, which is dense and is made up of protons that bear a positive charge. The electrons move around this nucleus in orbitals.

One of the most fundamental aspects in Ernest Rutherford's atomic theory pertains to the location in which the vast majority of an atom's mass is found; this, of course, was to be in the nucleus. This was one radical departure from previous theories that did not even yet understand the existence of the nucleus. Another aspect of Ernest Rutherford's theory was for it to detail that the number of protons in the nucleus was what defined the identity of the element. For example, an atom containing one proton is hydrogen; a two-proton atom is an atom of helium, and so forth.

The Ernest Rutherford atomic theory was a landmark within the scientific revolution that ultimately led to today's modern conceptualization of the atom. This laid the foundation for the greater advancement into the atom, which includes the development of quantum mechanics and the study of nuclear energy.

Ernest Rutherford's Discovery of the Proton

Apart from nucleus discovery, Ernest Rutherford made another key discovery: that of the proton. A proton is a tiny particle that carries a positive charge found in the nucleus of an atom. With the discovery of the proton by Ernest Rutherford, scientists were able to understand the components that made up the nucleus and how different elements were created.

Protons have a very important role; actually, they determine what element the atom will be. For example, an atom with one proton is a very light element—hydrogen. In the meantime, an atom with six protons is carbon, which can be found in all living things. The atomic number is defined as the number of protons in the nucleus of an atom and is the basis for the distinguishing characteristics of elements.

Another huge step forward came with the discovery of the proton by Ernest Rutherford. With it, scientists took one more critical step in understanding what matter is made of and how atoms are constructed.

Understanding Protons: What Are They?

Protons are the small particles found within the nucleus of an atom. Being positively charged particles, they are attracted, hence form bonds with other negatively charged particles such as electrons. A proton is one of the three important particles that constitute an atom, along with neutrons and electrons.

It is the number of protons in the atom's nucleus that causes each atom to be what it is, or in other words, which element an atom belongs to. For example, one atom whose nucleus carries one proton is hydrogen, and another very similar one with eight protons is oxygen. Thus, protons are highly important because they define the atom's identity.

Protons also create the positive charge within the nucleus. Being positively charged, protons attract electrons, which possess a negative charge. Attraction between the protons and the electrons keeps an atom in place.

The most monumental contribution to the understanding of atoms was made by Ernest Rutherford in the discovery of the proton. It informed scientists much more on the forces that held atoms together and how elements are finally made.

Mass of a proton

The mass of a proton is fantastically small! Perhaps the best way to attempt to visualize this is to weigh a single proton, which will be roughly 1.67 x 10^-27 kgs. That number probably makes very little sense, so let me put it in easier terms:

Take one penny and divide it into a billion pieces. Then, take one of those little pieces and divide it into another billion pieces. Now, imagine that one of those super small pieces has about the mass of a proton. That is just how tiny and light the proton is! Even as tiny as they are, protons play a huge role within the atoms of everything that surrounds us.

Later Life and Death of Ernest Rutherford

In the final analysis, after all his discoveries, Ernest Rutherford was still on the way to continue working as a scientist and a teacher. He later became a professor at the University of Manchester in England and through that became the directing head of a large number of new, youthful scientists who went on to further important discoveries.

He became director of the Cavendish Laboratory at the University of Cambridge in 1919 and thus returned to the place where he had once been a student. Subsequent to Rutherford's direction of the laboratory, named after the physicist Lord Kelvin, there were many other basic contributions to science, one of the most important being the discovery of the neutron. 

Ernest Rutherford won several Nobel prizes during his lifetime, such as in the field of Chemistry in 1908 due to his work on the structure of atoms. He was also knighted by the British government and hence became Sir Ernest Rutherford. He died on October 19, 1937 at the age of 66. He was interred in London's Westminster Abbey, an honor accorded to few of the most distinguished.

The Legacy of Ernest Rutherford

Ernest Rutherford left this world with a legacy, known in the scientific world. Human understanding at a level smaller than the submicroscopic the knowledge that Ernest Rutherford has found about the structure of the atom, nucleus, and proton is influenced by human thinking at that level. Even today, at schools, students are introduced to the atomic model and atomic theory developed by Ernest Rutherford and introduced to the students at the cradle of modern physics and chemistry.

Scientists expanded Ernest Rutherford's work in finding out the secrets of the atom and its binding forces. Most of the scientific developments that have been realized are based on his groundbreaking research.

Conclusion 

The importance of Ernest Rutherford is clearly seen. Ernest Rutherford was simply a genius scientist who has changed the perception of people about the atom and the universe. From his name, it is evident that his discoveries, mostly the atomic model of Ernest Rutherford, atomic theory, and the proton did change science and technology for good. We understand a great deal more regarding the elementary constituents of matter and the forces binding them together, in great part to the contributions from Ernest Rutherford. His legacy remains and it is inspiring for the researchers of the modern epoch being busy with discovering the secrets of the atom and the universe.

So think about those tiny particles that make up everything around you; remember Ernest Rutherford and his absolutely incredible contributions that he made to science!
