Question

Why covalent character of metal-halides increases from left to right in a period?

Answer 1

Answer:

$\huge\bold\star\pink{Answer}\star$

It decreases in periods as we go from left to right . it increases in groups as the electrons get further away from the nucleus the attractive forces bettween the positive charge of the nucleus and negative charge of the electrons decreases and they are easy to share with their atoms.

Answer 2

Answer:

Covalent character:

An electron is shared mutually by two atoms, in between these two atoms an ionic bond is present. In the periodic table, as we go down the group, the size of the halogens increases whereas its electro negativity decreases down the group.

The increase in covalent character is in the order of MF < MCI < MB < MI where, M refers to any alkali metals.
