Electrons orbit protons and neutrons because they are a much lighter particle (a proton weighs more than 2000 times as much as an electron) and because the negatively charged electron is attracted to the positively charged proton, and the attraction holds it on orbit (much as the gravitational attraction of the sun holds the planets in orbit). This arrangement works even without neutrons (as in a hydrogen atom) but the neutrons help to hold a nucleus together when there is more than one proton (and all protons electrostatically repel other protons).

Of what are atoms composed?
Atoms are composed of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus in energy levels.
What are the three essential parts of an atom?
Protons, Neutrons and Electrons. Protons and Neutrons form the nucleas, surrounded by a cloud of Electrons.
Three basic parts of an atom?
Protons, neutrons, and electrons are the three basic parts of an atom. Protons have a positive charge, neutrons carry no charge, and electrons have a negative charge and orbit around the nucleus of an atom.
What are the three main parts of the atom?
The three main parts of an atom are protons, neutrons, and electrons. Protons and neutrons are located in the nucleus, while electrons orbit around the nucleus in energy levels.
