Best ResponseYou've already chosen the best response.0NO,it has 7 electrons in the outermost orbitals since electrons from both 3s and 3p are calculated .So it is definetely a 7A element! More.. it has electrons on K L and M so the period is 3 it has 7 electrons on M (outermost ) so it's on the 17th or 7A group :) it's Cl
