Answer - PX2 Element 'P' with atomic number 56 will lose two electrons to form P^ 2+ ion with 54 electrons corresponding to the stable noble gas electronic configuration. Halogen gains one electron to formX^-1 ion. One P^2+ ion combines with two X^-1 ions to formPX2 . Note: In a neutral molecule, the total charge on cations is numerically equal to the total charge on anions.
