anions and protons ***
cations and anions

Which of the following has the highest melting point?

metallic compound
ionic compound
covalent compound ***
cations and electrons

Answer 1

nope, nope, I dont like any of the answers, nope

Metallic bonds are the force of attraction between valence electrons and the metal atoms. It is the sharing of many detached electrons between many positive ions, where the electrons act as a "glue" giving the substance a definite structure. It is unlike covalent or ionic bonding.
