Solution

An atom is composed of three types of subatomic particles: protons, neutrons, and electrons.

  1. Protons and Neutrons: These are located in the nucleus, which is the center of the atom. Protons carry a positive charge, while neutrons carry no charge. The nucleus is very dense and contains most of the atom's mass.

  2. Electrons: These are located outside the nucleus in regions called electron shells or energy levels. Electrons carry a negative charge and are much smaller than protons and neutrons. They move around the nucleus in orbits, similar to how planets orbit the sun.

  3. Arrangement: The arrangement of these particles is such that the protons and neutrons form the central core (nucleus) of the atom, while the electrons orbit around this nucleus. The number of protons in an atom determines the type of element it is. The number of electrons and their arrangement determine the atom's chemical properties, including how it bonds with other atoms.

  4. Balance of Charges: In a neutral atom, the number of protons (positive charges) is equal to the number of electrons (negative charges), resulting in a net charge of zero.

This is the basic arrangement of subatomic particles in an atom.
