Trend in electronegativity down a group
WebDown a group, to electronegativity decreases. Across a periodical, it increases. 1. Down A Group • As i move down a group, the number of energy levels increases. The valence e- cannot feel the pull of the nucleus as strongly. • The nuclear shielding also increases, shrink the pull from the favorable seed. (Note: this nuclear charge [i.e. # of p+] also increases … WebHalogens are elements found in group 7 of the periodic table.
