Composition of the nuclei of two atomic species X and Y are given as under
|
X
|
Y
|
|
| Protons | \(6\) | \(5\) |
| Neutrons | \(6\) | \(7\) |
Give the mass number of X and Y and state the relation between the two species?
Mass number \(=\) Number of protons \(+\) Number of
Mass number of X \(=\)
Mass number of Y \(=\)
Both X and Y have the same mass number (\(12\)) but different numbers of protons, so they are of different elements.
