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.

Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and typically a similar number of neutrons (none in hydrogen-1).Protons and neutrons are called nucleons.Over 99.94% of the atom's mass is in the nucleus.he number of neutrons defines the isotope of the element. The number of electrons influences the magnetic properties of an atom. Atoms can attach to one or more other atoms by chemical bonds to form chemical compounds such as molecules.
