प्रश्न
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?
उत्तर
X – 2e– —> X2-; when an atom has 6 electrons in its outermost shell and it accepts 2 electrons, it gets two negative charges.
