which type of substances have chemical bonds that are not directional and valence electrons that move freely…

Brief Explanations:

Metals have metallic bonds which are non - directional. In metals, valence electrons form a "sea of electrons" that can move freely between the atoms. Halogens form covalent bonds which are directional. Non - metals can form covalent or other types of directional bonds. Salts have ionic bonds which are electrostatic and not characterized by a sea of freely - moving electrons like metals.
