question_answer 60)

  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?

Answer:

  Element X has 6 electrons in the outermost shell. In order to acquire noble gas configuration, element/requires 2 electrons. So, the charge on the anion so formed is -2.
