Question

2. Write the electronic configuration
of any one pair of isotopes and
isobars.​

Answer 1

Answer:

The electronic configuration of any one pair of isotopes and isobars are

Explanation:

• A pair of isobars is 40^18Ar and 40^20Ca. 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.
• 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.
