molecule

The ion differs from the molecule, the corpuscle and the atom in that it is an ion.

A molecule is the smallest particle of a compound which can exist.

The ions formed by the dissociation of any molecule are of two kinds.

This will be the sum of the weights of the nitrogen atoms in the molecule.

We cannot be good to an atom of hydrogen, or unjust to a molecule of water.

Of what nature will be that molecule supposed to possess life by itself?

It is the molecule, without which the laws of chemistry would be miracles.

If these were to be altered in the least, it would no longer be a molecule of hydrogen.

This molecule is correlated, as it were, to the aggregate to be formed.

They are merely atoms in the molecule—a tiny fragment of perfection.
