Use the periodic table to determine the number of valence electrons in each of the following elements. Na:
E:
V:
Ar:

Na= 1, Ar= 8, V= 5, F= 7

Explanation:
You can determine the number of valence electrons in an element by looking the the group/column # on the periodic table. Elements in the same family/ group are organized by columns (vertical). Elements in the same column have the same number of valence electrons (electrons of the outermost shell) and consequently similar properties.
Simply put, GROUP #= # VALENCE E-

There are exceptions to this, especially when determining the amount of valence electrons in elements that are in a compound or in transition metal elements. For transition metals (that have different oxidation states- different # of valence electrons for the same element) I’d just look it up

You can still be friends with each other. you don't have to date since he likes someone else. just stick to being friends for now
