What is Metal? Properties, Types and Examples Explained

Metals are an essential part of our everyday lives, right from the utensils in our kitchen to the vehicles we travel in. But what exactly makes metals so special, useful, and widely used? Metals are solid, shiny, and strong materials that are naturally found in the Earth’s crust. Interestingly, because of this, they are known for their ability to conduct heat and electricity, which is why they are used everywhere from cooking utensils to electric wires.

This article focuses on the metals in the simplest form, along with their types and properties, explained with our daily life examples.

What Are Metals?

Metals are naturally occurring elements found deep within the Earth’s crust, usually in the form of ores. But how are they processed? The fact that these ores are mined and processed to extract pure metals. 

The simplest metals are inorganic, meaning they are not formed from living organisms. They usually have a shiny appearance, are solid at room temperature (except mercury), and possess strong physical and chemical properties that make them useful in almost every industry.

But how does the Occurrence of Metals in nature happen? 

Metals are found in two forms:

• Native State: Unreactive metals like gold and silver exist freely in nature.

• Combined State in which reactive metals like aluminium, iron, and sodium exist as compounds.

• Mineral Ores, like rocks containing high amounts of metal compounds, are called ores.

Let's have a closure on the key points about metals:

• Most metals are shiny or lustrous.
• Almost all are solid at room temperature.
• They are strong, durable, and good conductors of heat and electricity.
• Many metals occur mixed with other elements in ores, not in pure form.

Some common metals we use daily include:

• Iron is used for tools, machinery, and buildings
• Copper is used in wires, utensils, and electrical parts
• Gold and Silver in jewellery, coins, and electronic components
• Aluminium in cans, utensils, aeroplane parts
• Zinc in batteries, galvanising iron
• Magnesium in firecrackers, alloys

Some Special Cases:

• Sodium & Potassium are soft metals cut with a knife
• Mercury is the only liquid metal at room temperature

Types of Metals

Apart from the fact that how we see metals is not enough, these metals are classified into four more 

• Some metals, like ferrous metals (iron, steel), are magnetic and used for building strong structures. 
• Non-ferrous metals such as copper and aluminium resist rust and are lightweight, making them perfect for wiring or aircraft. 

• Precious metals, gold, silver, and platinum are prized for beauty and rarity.

• Alloys, mixtures like bronze or stainless steel, combine strengths for specialised purposes.

Physical Properties of Metals

Metals show certain characteristic physical features that make them unique:

• Lustre that is metals have a shiny appearance when polished. This is why gold and silver are used in jewellery.

• Most metals are hard and cannot be broken easily. Iron and copper are classic examples.
(Exceptions: Sodium and potassium are soft enough to be cut with a knife.)

• It's the property of metals called malleability, in which Metals can be hammered into thin sheets without breaking.
Example: Aluminium foil.

• The property ductility, in which Metals can be stretched into thin wires.
Example: Copper and aluminium wires used in electrical circuits.

• The fact that Metals are excellent conductors of heat and electricity.
This is why cooking utensils and electrical cables are made of metals.

• Metals show High Melting and Boiling Points as they require a lot of heat energy to melt.
Example: Iron melts at around 1538°C.

• Most metals have high density, meaning they are heavy for their size.

Chemical Properties of Metals

• Reaction with Oxygen: Metals react with oxygen to form metal oxides.
Example:
Magnesium + Oxygen → Magnesium oxide

• Reaction with Water: Some metals react vigorously (like sodium), some slowly (like iron), and some not at all (like copper).

• Reaction with Acids: Metals react with acids to form salt and hydrogen gas.
Example:
Zn + HCl → ZnCl₂ + H₂↑

• Reaction with Bases: Certain metals react with strong bases (like NaOH) to form complex compounds.

• Reactivity Trend: Highly reactive metals react more quickly and vigorously compared to less reactive ones. This is explained by the Activity Series.
