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 (or center) of an atom is made up of protons and neutrons.

Detailed explanation-3: -Inside protons and neutrons are two more subatomic particles: quarks and gluons. Quarks are in the fermion category of fundamental particles, and there are three of them in each proton and neutron. They are bound together by gluons, which are categorized as bosons.

Detailed explanation-4: -Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.

Detailed explanation-5: -Tritium is an isotope of hydrogen whose nucleus Triton contains 2 neutrons and 1 proton.
