Solution

To achieve the octet configuration, the atom of the element X can lose 1 electron from its outermost shell.
Therefore, its valency is 1.

If 1 electron is removed from the atom, then one electron will be less than the number of protons. So, there will be one proton extra than the electrons. Therefore, a positive charge (+1) is created on the ion.
