found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons. Atomic num...
If you have an element name orsymbol, use aperiodic tableto find the atomic number. There may be many numbers on a periodic table, so how do you know which one to pick? The atomic numbers go in order on the table. While other numbers may be decimal values, the atomic number is alway...

Hydrogen (H), on the other hand, has only one proton in its nucleus, so its atomic number is 1, and it appears at the beginning of the periodic table. The atomic number of each element, which is the number of protons in its nucleus, appears next to its symbol in the table. If ...
Outside the nucleus of an atom: The volume of the rest of the atom (surrounding the nucleus) is occupied by the other type of sub-atomic particle, which is called an electron, or rather (in all cases except for hydrogen) electrons because there are many electrons per atom. Electrons have...
