In the atom of an element X, 6


In the atom of an element $X, 6$ electrons are present in the outermost shell. If it acquires noble gas configuration by accepting requisite number of electrons, then what would be the charge on the ion so formed?


With six (6) electrons in the outermost shell, the atom of the element needs two (2) electrons more to have eight (8) electrons in the outermost shell. The ion $\left(x^{2-}\right)$ has $-2$ units charge.
