This form of periodic table is more congruent with the order in which electron shells are filled, as shown in the accompanying sequence in the left margin (read from top to bottom, left to right). The placement of helium (a noble gas) above beryllium (an alkaline earth metal) ordinarily attracts strong criticism from chemists. — Preceding unsigned comment added by 103.29.118.228 (talk) 13:00, 18 November 2013 (UTC)Reply

A query with doc pages

Thanks, very careful. Since this is a second doc page after a template merge, I've put a speedy tag on it. -DePiep (talk) 08:18, 23 March 2017 (UTC)Reply
