each group of the Periodic Table consists of elements that resemble each other. for instance Lithium, sodium, potassium, and a few more a grouped together, are called the alkali metals. These are all highly reactive, thus they are in a group. Furthermore group also determines the number of valence electrons are present in some cases. Hope that answered your question.

How do you determine valence from the periodic table?
Each group/family on the periodic table can determine valence electrons by the last number of the group/family number, like helium. It's a noble gas that has 8 valence electrons because it's on the 18 family/group
