- Masses of other atoms are expressed with respect to the atomic mass unit. For example, the mass of an atom of 1 H is 1.008 u, the mass of an atom of 16 O is 15.995 u, and the mass of an atom of 32 S is 31.97 u.
- Atoms on row 1 have their valence electrons on the 1st energy level. Atoms on row 2 have their valence electrons on the 2nd energy level. Atoms on row 3 have their valence electrons on the 3rd energy level. This pattern repeats all the way through the end of the periodic table on row 7.
