You don't have to remember these numbers, because a Periodic Table will be supplied to you in every test of chemistry and physics. You do have to be able to USE the Table.
Nuclear protons are conceived to have a positive charge. For a NEUTRAL element, there thus must be an equal number of negative charges, and these are supplied by
Also contained in the nuclear core, are various numbers of neutrons. Because a particular element may have various numbers of neutrons, this gives rise to the existence of
And so we identify the given nuclides, armed with a Periodic Table. All I do is look up the number
Please don't be blinded by science, and a few unfamiliar terms. The concept is fairly simple, and if you persist you will master it. A final question. We have
