प्रश्न
Composition of the nuclei of two atomic species A and B is given as under :
| A | B | |
| Protons : | 18 | 20 |
| Neutrons : | 22 | 20 |
Give the mass numbers of A and B. What is the relation between the two species and which element or elements they represent ?
उत्तर
Mass number is the sum of the number of neutrons and the number of protons. So, mass number of A and B is 40. As the mass number of A and B is same, the two are isobars.
Therefore, A represents (`""_18^40"Ar"`) Argon while B represents (`""_20^40"Ca"`) Calcium.
