WebAnd so for this video, we're only talking about the valence electrons for elements in the main groups. When we talk about the main groups, you're using the one through eight system for classifying groups. So one, two, three, four, five, six, seven, and eight. So we're going to ignore the other way to number the groups. WebThe Halogens There are six elements in Group VIIA, the next-to-last column of the periodic table.
