Question

The atom of an element 'A' has three electrons in the outermost shell.

It loses one of these to the atom of another element 'B'.

What will be the nature and value of charge on the ion which results from 'A' ?

Answer 1

Since the atom, $\text{'}\mathrm{A}\text{'}$ has lost one electron.

The ion formed will be positive(cation) and will have a +1 charge.

It can be represented as ${\mathrm{A}}^{+}$.
