Hydrogen bonding

Ionic bonding

Metallic bonding

Weak dispersion forces

Dipole-dipole, dispersion, hydrogen bonding

Dispersion, hydrogen bonding, dipole-dipole

Dispersion, dipole-dipole, hydrogen bonding

Hydrogen bonding, dipole-dipole, dispersion

molten or dissolved in water

a solid only

frozen

never

a mixture of ionic and metallic

ionic

molecular (covalent)

metallic

Ionic crystals contain mobile electrons

In metals the mobile electron sea lets ions slide past one another and stay bonded, while shifting an ionic lattice brings like charges together and causes repulsion

Metals are always softer than every ionic solid

Metals contain no bonds

$\text{NH}_3$

$\text{CH}_4$

$\text{CO}_2$

$\text{Cl}_2$
