hope it helps....

Answer 2

Answer:

Isobars have different atomic numbers. ... As both have same mass number which indicates same number of nucleons i.e. Neutrons and protons, they are isobars. The atomic number of calcium and argon are 20 and 18 respectively, but the mass number of these elements is 40. So (B) name is given to such a pair of elements.
