Question

One electron is present in the outermost shell of the atom of an element $\mathrm{X}$. What would be the nature and value of charge on the ion formed if this electron is removed from the outermost shell?

Answer 1

Charge of the ion:

• A cation will be formed when an electron is removed from the outermost shell and the charge of the element will be $+1$.
• When a single electron in an element $\mathrm{X}$’s outermost shell is removed, the atom forms a positively charged ion with a charge of $+1$.
