How to valence electrons increase
WebReactivity Reactivity relates to how willing an element is to give up or gain an electron For metals Reactivity increases as you move down and left It increases going down because the atomic size increases as you go down. Because its bigger, the attraction of the electrons on the outer (valence) shell is weak. WebAn atom with one or two valence electrons more than a closed shell is highly reactive, because the extra valence electrons are easily removed to form a positive ion. An atom with one or two valence electrons fewer than a closed shell is also highly
