What does the periodic table tell us about the elements?

WebThe number of valence electrons present in a neutral atom is determined by the element's group (column) on the periodic table. Every element in a given group has the same number of valence electrons. For elements in the main groups (1-2, and 13-18), the number of valence electrons increases when moving from left to right along any period (row). WebTo determine the group, we need to understand some rules: 1. If the element is in s block, then the group number is equal to the number of valence electrons.
