What do you use on the periodic table to determine the number of valence electrons?

To determine the number of valence electrons, you look at the group number of an element on the periodic table.


How can one determine the number of valence electrons for an element on the periodic table?

To determine the number of valence electrons for an element on the periodic table, look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.

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
