2. Physics

An atom with 5 electrons in its outer shell is

  • trivalent.
  • univalent.
  • pentavalent.

Explanation from PART66Online

Valency follows the number of electrons in the outer shell, so an atom with five such electrons is pentavalent. Three would make it trivalent and one univalent, so five corresponds to pentavalent.
