The easiest way to use Query Atoms, different Query Groups and Query Atom Properties is to find them on the Periodic Table's Advanced tab.

What is an atom’s atomic number? The number of protons in the nucleus of an atom determines an element’s atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1.
