Question

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

Answer 1

Isotopes:

Isotopes are atoms of the same element having the same atomic number but different atomic masses.

The difference in the masses of isotopes of an element is due to the different number of neutrons in the nucleus.

Since all the isotopes of an element have identical electronic configuration containing the same number of Valence Electrons therefore all the isotopes of an element show identical chemical properties..


Isobars:

Atoms of different elements with atomic number for the same mass number are called isobars.

Isobars have different chemical properties because they have different atomic numbers & their electronic configuration are different.

____________________________

Two isotopes of carbon are :

12C6 & 14C6
Electronic configuration are:

12C6= 2,4

14C6= 2,4


Two isobars of calcium and Argon are:

40Ca20 & 40Ar18

Electronic configuration are:
40Ca20= 2,8,8,2

40Ar28= 2,8,8
