how many valence electrons does an element in column 15 have? describe the charge on the ion and how it can be determined.

5

Explanation:

The number of valence electrons an element in column 15 would have is 5. The valence electrons in an atom are the outermost shell electrons found within an atom.

These electrons resides in the highest energy level of the atom.

The main group number of periodic column gives the number of valence electrons they contain.

For column 15, it is also group 5 and the valence electrons is 5.

Also, we can determine this by using electronic configuration of the elements in the group.

answer: i would say b.
