The noble gases have weak interatomic force, and consequently have very low melting and boiling points. They are all monatomic gases under standard conditions, including the elements with larger atomic masses than many normally solid elements.
In fact, because hydrogen is so much less electronegative than oxygen, there is a strong intermolecular force known as hydrogen bonding present in water. Hydrogen bonding is an exceptional case of dipole-dipole interactions. In oxygen gas, intramolecular forces are nonpolar covalent. The forces are covalent for the same reasons as above: oxygen is a nonmetal, and in oxygen gas, oxygen is bonded with only oxygen.
