How to Find the Atomic Number for Atoms/Elements

Being able to find the Atomic Number (also called the Proton Number) for elements is an essential chemistry skill. To find the Atomic Number all you need is a Periodic Table of the Elements.
For each element on the Periodic Table, the Atomic Number is the whole number above the element symbol. For example, the Atomic Number for Sodium (Na) is 11. For Hydrogen, H, it is 1.
The Atomic Number is defined as the number of protons that a particular atom has in its nucleus. For Sodium (Na) there the Atomic Number is 11. That means that there are 11 protons in the nucleus for an atom of Na. This is unique to Na, it is the only atom with 11 protons. Any more or less would not be Na.
For neutral elements (all the elements on the Periodic Table are neutral) the Atomic Number also equals the number of electrons for the atom. Since Na has an Atomic # of 11 it has 11 protons AND 11 electrons.

I'm thinking of a number that is 36. Can you tell me what number I'm thinking of? (15 second pause). I'm thinking of 36.
