V valence electrons





Core vs. Valence Electrons Exercise. Exercise 3.1: Use the facts that all of the electrons in an atom are either core or valence electrons, 

In chemistry, valence electrons are the electrons that are located in the outermost electron shell of an element. Knowing how to find the number of valence electrons in a particular atom is an important skill for chemists because this information determines the kinds of chemical bonds that it can form and, therefore, the element's reactivity.
