Question

X has 2 valence electron . What should be the nature and the value of the ion formed if electrons are removed from the outermost shell?

Answer 1

X has 2 valence electrons that means that there are 2 electrons in it's outermost shell..

When these electrons are removed,

Atom will aquire positive charge of 2 units.

So,

It will become

X (2+) cation.....

Answer 2

Bcoz of 2 valence electrons X is metallic in nature, I.e., it can easily lose electrons .

On removing the electrons from its valence shell it will become an ion X2+ with positive charge of 2.
