What are the subatomic particles of an atom? a. rotons, neutrons, and nucleus b. protons, neutrons, and electrons c. electrons, orbitals, and neutrons d. electrons, neutrons, and nucleus

B - Protons, Neutrons, and Electrons

Subatomic particles are the smallest particles within an atom.

A would be incorrect as the Nucleus is composed of said subatomic particles (Protons and Neutrons).

C is incorrect as Orbitals are used to describe the amount of electrons based on each shell, thus, deeming them inaccurate to the term of subatomic particles.

D is incorrect as, once again, the Nucleus is comprised of subatomic particles and is not a subatomic particle itself.

Hope this helps!

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
