the electron
The smallest and least energetic path of an electron around a nucleus is the ground state, or lowest energy level. In this state, the electron occupies its lowest energy orbital closest to the nucleus.
Electrons are the particles that move around the nucleus in constant and random motion.
If you are talking about the nucleus of an atom, the particles that 'orbit' around the nucleus are electrons.
Electrons are the atomic particles that move around outside the atom's nucleus. These negatively charged particles orbit the nucleus in specific energy levels or shells.
Electrons are what form the cloud around a nucleus

Electrons are the particles found in shells around a nucleus. They are negatively charged and move in orbitals at specific energy levels.
Nucleus consists of two types of particles - protons and neutrons. these are together called nucleons. Electrons revolve in shells around the nucleus.
For an atom of xenon, the number of particles in the nucleus would be the sum of the protons and neutrons. Xenon has 54 protons and usually around 78 neutrons, so the total number of particles in the nucleus would be around 132.
