metallic bonding
1. Most metals have very few __________ in their outermost energy shells, and some have vacant outer electron orbitals. That means its valence electrons are _______________ and free to move around.

2. When metals are next to each other, the valence electrons don’t just stay on their own atom; they roam around the ________________________.
