Detailed explanation-1: -Protons and neutrons are present inside the nucleus of an atom while electrons revolve around circular orbits.
Detailed explanation-2: -The nucleus itself is generally made of protons and neutrons but even these are composite objects. Inside the protons and neutrons, we find the quarks, but these appear to be indivisible, just like the electrons.
Detailed explanation-3: -Neutrons, along with protons, are subatomic particles found inside the nucleus of every atom. The only exception is hydrogen, where the nucleus contains only a single proton. Neutrons have a neutral electric charge (neither negative nor positive) and have slightly more mass than positively charged protons.
Detailed explanation-4: -There are three subatomic particles in your standard model of an atom: protons, neutrons, and electrons. Protons and neutrons reside in the nucleus. Electrons orbit the nucleus.
Detailed explanation-5: -A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below).
