a) K. Fajan
b E Bethe
c) Kossel
d) Hund​

Answer 1

Answer:

(c) Kossel

Explanation:

The formation of ionic was first time explained by Kossel.

Answer 2

The formation of the ionic bond was first time explained by C) Kossel

Kossel:

W. Kossel was the actual discoverer of the ionic bond.

Explanation for incorrect options:

a) K. Fajan:

Few ionic bonds have partial covalent properties, which were first discussed by Kazimierz Fajans in 1923. He does not explain the formation of ionic bonds.

b) E Bethe:

He was the head of the Theoretical Division at the secret Los Alamos laboratory, where the first atomic bombs were developed. He does not explain the formation of ionic bonds.

d) Hund​:

Hund discovered the tunnel effect, also known as quantum tunneling, and Hund's rule of maximum multiplicity. He does not explain the formation of ionic bonds.

Hence, Kossel was the first to explain the formation of an ionic bond.
