Question

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

Answer

1. Pair of Isotopes (Carbon-12 and Carbon-14):
Isotopes have the same atomic number, so their electronic configuration is identical.

  • Carbon-12 ({}^{12}_{6}C): 2, 4

     

  • Carbon-14 ({}^{14}_{6}C): 2, 4

     

2. Pair of Isobars (Calcium and Argon):
Isobars have different atomic numbers, so their electronic configurations are different.

  • Calcium ({}^{40}_{20}Ca): 2, 8, 8, 2

     

  • Argon ({}^{40}_{18}Ar): 2, 8, 8
