Question

An element 'X' contains 6 electrons as Valence electron.
What is the valency of X?​

Answer 1

Answer: -2 in s valency

Explanation:no. Of electron =no. Of proton = atomic no.

So you said that 6 elctron are in valence shell . So, the valency is - 2.

Answer 2

Answer:

it's answer is 2

Explanation:

As valence electrons means the electrons in the outermost she'll then if we follow octet rule then we will subtract the valence electrons from the total no. of electrons.

8-6=2.
