Question

Write the number of valence electrons of atoms of an element which shows catenation.​

Answer 1

Answer:

As we move from top to bottom in a group, the number of valence electrons remains same because a group is defined such that their valence shell configuration is same. Hence, valence electrons remain same but valence shell changes.

Answer 2

Answer:

Valence is an older term that describes how many other atoms an atom can bond with. Valence electrons are the number of outer shell electrons an atom has.
