Hydrogen has three isotopes, protium (H11), deuterium (H21 or D21) and tritium (H31 or T31). The chemical properties of isotopes are similar but their physical properties are different. They have same atomic number but different mass numbers.
The three subatomic particles, electrons, protons and neutrons, in the three isotopes of hydrogen are given in the following table:
your 2 answer
(a) A pair of isotopes of chlorine is 3517Cl and 3717Cl. The atomic number of both the isotopes is the same 17. So, the electronic configuration of both these isotopes will be 2, 8, 7.
(b) A pair of isobars is 4018Ar and 4020Ca. The atomic number of orgon (Ar) is 18, so its electronic configuration will be 2, 8, 8. The atomic of calcius (Ca) is 20, so its electronic configuration will be 2, 8, 8, 2.
