Question

one electron is present in the outer most shell of the atoms of an element x what would be the nature and value of charge of an ion formed if this electron is removed from the outer most shell​

Answer 1

An element X is a metal because one electron is present in the outermost shell i.e., 1 valence electron. When this valence electron is removed from the outermost shell, a cation (positive ion)will be formed with a charge of + 1.

Answer 2

Answer:

Element X will be a metal cause 1 electron in outermost shell & will form a cation (+ve) and will complete it's octate.

It will be a highly reactive element when it has only one electron to lose
