The ability to conduct electricity in the solid state is a characteristic of metallic bonding. This characteristic is best explained by the presence of

• high ionization energies

• mobile protons

• high electronegativities

• mobile electrons

The electronegativity value of an element is a measure of the atom's

• degree of conductivity

• ability to attract electrons

• ability to attract protons

• degree of stability

Which intermolecular force of attraction accounts for the relatively high boiling point of water?

• covalent bonding

• hydrogen bonding

• ionic bonding

• metallic bonding

A chemical bond between two atoms results from a simultaneous

• repulsion by the protons in the two nuclei

• attraction by the protons for the neutrons

• repulsion by the valence electrons of the atoms
