List 4 types of information that are given in each box of the periodic table:

1) the element symbol, and thus name. For example, H is hydrogen, C is carbon and Fe is iron.

2) The atomic number, which is equal to the number of protons in the nucleus.

3) Since each proton has a + 1 charge, you can also figure out the number of - 1 electrons in the neutral atom.

4) The atomic mass, in atomic mass units, which is an average of 1 or more isotopes of the element.
