  • Q6
    How are valence electrons related to reactivity?
    The closer the number of valence electrons is to 1 or 7, the higher the reactivity
    The fewer valence electrons, the higher the reactivity
    The more valence electrons, the lower the reactivity
    The closer the number of valence electrons is to 3 and 4, the higher the reactivity
