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?
In order to achieve an octet or to achieve the nearest noble gas configuration, the atoms react. This is done by gaining, sharing or losing electrons. In this atom, 6 electrons are present in the outermost shell. In order to complete an octet, it has to gain 2 more electrons. This will result in the formation of a negative ion. The ion thus formed will have charge equal to -2.
