The valence electrons found in metals are different from nonmetals because select all that apply: a. metals can conduct electricity b. metals have immobile electrons c. the valence electrons of nonmetals cannot roam freely d. metals are able to share electrons with other metals

The answer is; A & C

The valence electrons in the metal atom in the lattice structure can delocalize and move freely. The electrons are "loosely" connected with their parent atom in the metallic bond because most metals have excess electrons in their outer orbitals above the stable configuration. The electrons mainly occur in higher densities around the positively charged nuclei of surrounding metal atoms and move freely between these spaces.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
