1) The Class Teacher Has Given the Students the Number of Neutrons and the Atomic Number of the Following Element. He Also Taught Them That-
Here Is the List of the Elements. Read the List Carefully and Find Their Atomic Mass. Fill In the Blank Rows. One Is Done for You as an Example.
Element | Atomic Number (Z) | Number of Protons (N) | Atomic Mass (A) |
Technetium | Z = 43 | N = 55 | A = N + Z = 55 + 43 = 98 |
Promethium | Z = 61 | N = 84 | |
Polonium | Z = 84 | N = 121 | |
Radon | Z = 86 | N = 132 | |
Astatine | Z = 84 | N = 125 | |
Curium | Z = 96 | N = 151 | |
Fermium | Z = 104 | N = 157 | |
Rutherfordium | Z = 104 | N = 157 |
Element | Atomic Number (Z) | Number of Protons (N) | Atomic Mass (A) |
Technetium | Z = 43 | N = 55 | A = N + Z = 55 + 43 = 98 |
Promethium | Z = 61 | N = 84 | A = N + Z = 61 + 84 = 145 |
Polonium | Z = 84 | N = 121 | A = N + Z = 84 + 121 = 205 |
Radon | Z = 86 | N = 132 | A = N + Z = 86 + 132 = 218 |
Astatine | Z = 84 | N = 125 | A = N + Z = 85 + 125 = 210 |
Curium | Z = 96 | N = 151 | A = N + Z = 96 + 151 = 247 |
Fermium | Z = 104 | N = 157 | A = N + Z = 100 + 157 = 257 |
Rutherfordium | Z = 104 | N = 157 | A = N + Z = 104 + 157 = 261 |
