Protons are subatomic particles that, along with neutrons, comprise the nucleus or central portion of an atom. The rest of the atom consists of electrons that orbit the nucleus, much as Earth orbits the sun. Protons can also exist outside an atom, in th
An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Each atom has a center nucleus, where the protons and neutrons are densely packed together. Surrounding the nucleus are a group of orbiting electrons. ...
An element's atomic mass is equal to the sum of the individual particle masses of an atom. Atoms have three basic particles which include protons, neutrons, and electrons. The standard unit for measuring atomic mass is the Dalton (u). ...
