Other particles exist as well, such as alpha and beta particles (which are discussed below). In physical sciences, a subatomic particle is a particle that is smaller than an atom. Protons can be produced via the removal of an electron from a hydrogen atom. Shoot a charged particle like a proton perpendicularly through a magnetic field, and the field will push it sideways so it circles at a frequency that reveals the particle’s mass. Electrons - The Sub-Atomic Particles. The mass of an atom is the sum of the number of protons and neutrons. Protons are positively charged particles whereas neutrons do not carry any charge.
