Question

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

Answer 1

Since 6 electrons are already present in the outermost shell of the atom, this element requires two more electrons in order to acquire the noble gas configuration. When the atom accepts 2 more electrons, the charge on the ion formed would be -2.
