Answer» YeaExplanation:As we go down the group the VALENCE remains the same becoz the ELECTRONS enters into the same sub shell or the same outermost shell or u may ALSO called it as the valence for e.g., in grp1 elements-alkali metals have valence ns1 , grp 2 elements have valence ns2 and the grp 18 HALOGEN family valence ns1-6. all the elements in these groups have the same outermost valency .ok |
