I might add that what differences one element from another i sthis number of protons. And just that number.

Every element is discovered or labeled by their "Proton" number... which is the Atomic Number of the Molecule!!! For example.. if u look up "Oxygen" -- it has 16... meaning that ANY Molecule in the world that has 16 Protons-- IS an OXYGEN, Regardless if it doesnt taste, look, feel, act, or think like an Oxygen!!
its a TAG -- Identity -- label..
Another Example:
Hydrogen has an Atomic Number of 1..... so when we scan a NEW element that looks funny or wierd or combine with something else... we find that an element has 1 proton, WE KNOW that it is a HYDROGEN!!.. like a social security number :) lol unless u r illegal!

The atomic number is equal to the number of protons in an atom's nucleus. The atomic number determines what element an atom is. For example, an atom with 8 protons is oxygen(I chose that specifically to correct one of the posters above).

Atomic number also means the number of protons in the atom. And when the atom is nuetral, it is also the number of electrons in that atom.

The atomic variety supplies the range of protons contained in the nucleus and, for the impartial atom, the range of better-nuclear electrons. The atomic variety subtracted from the mass variety supply the range of neutrons contained in the nucleus.
