Group 1 elements all have the same valence or outer shell electrons in their outer shells (one valence electron). This gives them similar properties. Group 2 elements all have 2 valence electrons in their outer shells. This also gives them similar properties. Not all of the groups, however, hold true for this pattern.

For Groups 1, 2, and 13-18 on the Periodic Table, elements within the same group have the same number of valence electrons (helium is an exception) and therefore similar chemical properties. (3.1z) The succession of elements within the same group demonstrates characteristic trends: differences in atomic radius, ionic radius, electronegativity ...

Chemistry 1: Classification of Elements Worksheet
Puzzle #1: Elements that are in the same group are: AYHES, QDKLU, WVRT, JBIF, PNGX, OMCZ. Clues: Element T has an oxidation number of -2 (it needs 2 more electrons to become stable). Element U has a larger atomic radius than element Q. Element U does not follow the periodic trends like the other group A elements do.
