If you want to find out what the most sold item is on ebay then do your research. Look around on ebay and compile a list. I would not want to compete with others who are already selling the most popular items. As the person stated you will have plenty of competition and will have to lower your prices.
An atom is made from a nucleus surrounded by electrons. The nucleus contains protons and neutrons. Isotopes are atoms that have the same number of protons, but different numbers of neutrons.An early model of the atom was the plum pudding model.It was disproved by Rutherford's scattering experiment and replaced by the nuclear model.he nucleus contains protons and neutrons.

The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron. If you had very, very good eyes and could look at the atoms in a sample of hydrogen, you would notice that most of the atoms have no neutrons, some of them have one neutron and a few of them have two neutrons.
