The main groups of the periodic table

SpletPeriodic Table: The periodic table is a system for arranging materials. It's worth noting that they're organized into columns and rows. 'Periods' are the horizontal rows that run from left to right, while 'groups' are the vertical columns (going from up to down). Different groups are present in the periodic table: The Alkali Metals Splet10. avg. 2024 · The Group IIA elements, the alkaline earths, have low electron affinity values. These elements are relatively stable because they have filled s subshells. Group VIIA elements, the halogens, have high electron affinities because the addition of an electron to an atom results in a completely filled shell.
