HEL What does the number of valence electrons tell you about the reactivity of the element?

a) If an element has 1 or 7 valence electrons, then it is the most reactive.
b) If an element has 2 or 8 valence electrons, then it is the most reactive.
c) If an element has no valence electrons, then it is the most reactive.
d) There is no connection between valence electrons and reactivity
