Question

If an atom has 6 valence electrons, how many electrons does it need to gain to achieve a stable electron configuration?

Answer 1

Answer:

2 electrons does it need to gain to achieve a stable electron configuration

Explanation:

Valance electron:

The electrons which are present in the outer most energy level are known as valance electron. This can be calculated by the group number of the element. Generally the group number is same as the valance electrons of any elements.

Octet rule: Generally all atoms will lose, gain or share electrons to attain 8 valence electrons; the electron configuration of the nearest noble element.

If an atom has 6 valence electrons; to get stable electron configuration of the nearest noble element require 2 electrons.

2 electrons does it need to gain to achieve a stable electron configuration

Answer 2

it would need to gain 2 more for it to achieve a stable configuration

the best way to remember this is the noble gasses all have 8 valence electrons and that they are the most stable elements on the periodic table
