The protons and neutrons are found in the nucleus of every atom. Electrons (negatively charged) are found in a cloud surrounding the nucleus of every atom. read more
Atoms are made up of even smaller, subatomic particles called protons, neutrons and electrons. By studying the light given out by elements, scientists have found out about the structure of atoms, and even discovered new elements. The number of protons in the atom of an element determines its place in the periodic table. read more
Protons are found in the nucleus of an atom, along with the neutrons. Electrons orbit the nucleus. read more
