We could weigh 1.008 grams of hydrogen and 35.453 grams of chlorine, and they would match up exactly right.

By Rutherford's calculations, the nucleus in an atom is like a BB in a boxcar. Almost all the mass of an atom is concentrated in the tiny nucleus.Most of the particles went straight through the gold.It was like shooting a rifle into a thin line of trees.The mass of a proton or neutron is 1.66 E -24 grams or one AMU, atomic mass unit. This number is a billionth of a billionth of a billionth of a gram.It is not possible for anyone or any machine that uses light to actually see a proton using visible light.The wavelength of light is too large to be able to detect anything that small.

The integer that you find in each box of the Periodic Chart is the atomic number.

It is oversimplifying only a little to say that this number is the number of protons plus the average number of neutrons in that element. The number of neutrons in the nucleus of an element can be different, though. Carbon 12 has six protons (naturally, otherwise it wouldn't be carbon) and six neutrons. This carbon 14 when taken into plants as CO will also be taken into animals.

The number is called the atomic weight or atomic mass. We can find out how much carbon 14 that normally is in a living plant or animal and from there we can find the actual amount of carbon 14 left in a plant or animal long dead.

On a periodic chart you may see some atomic weights that are integers or in parentheses.

These are usually on the very large or very rare or very radioactive elements.

Each element fits neatly into its niche in the Periodic Table. Types of an element in which every atom has the same number of protons and the same number of neutrons are called isotopes. Any carbon 14 that was made at the time the earth was formed is now almost all gone.
