A.they have mobile valence electrons
B.they have mobile protons
C.they chase mobile cations
D. Their crystal structures can be rearranged easily.

What are the weakest attractions between molecules?
A.ionic forces
B.van der waals forces
C.covalent forces
D.hydrogen forces

Which of the following correctly provides the name of the element, the symbol for the ion, and the name of the ion?
A.fluorine F+, fluoride ion
B.zine Zn+, zincate ion
C.copper Cu+, cuprous ion
D.sulfur,S+, sulfurous ion

Ionic compounds are made up of ions. Ionic compounds are formed when metals donate electrons to nonmetals. They have high melting and boiling points and are good electrolytes. However, they do not have low melting points.

Metals are bonded together by a metallic bond. A metallic bond consists of metal cations and a sea of valence electrons. This sea of free valence mobile electrons are the reason why metals are good electrical conductors.

Molecules of a substance in a particular state of matter are held together by intermolecular forces. The strength of different intermolecular forces vary. However, the weakest intermolecular force is van der waals forces.

When atoms of elements loose or gain electrons they form ions. Positive ions are formed by electron loss while negative ions are formed by electron gain. The correct name of the element, the symbol for the ion, and the name of the ion in the list is; copper, Cu+, cuprous ion
