You can find all of these answers by looking at your copy of the periodic table of the elements. Atomic number = number of protons = number of electrons Atomic mass = number of protons + number of neutrons For carbon, then, the atomic number is 6, so the number of protons and electrons is also 6. Since the atomic mass of carbon is 12, then the number of neutrons is also 6 (12 - 6 = 6). Now, see if you can do the rest on your own. Answered by Shelia Schmig 1 year ago.
oxygen has an atomic mass of 16, it has 8 protons and 8 electrons. and 8 neutrons hydrogen has an atomic mass of 1, it has no neutrons, 1 proton, 1 electron, and 0 neutrons. i think that's right :s Answered by Marcelene Wengler 1 year ago.
