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.

The Milankovitch theory postulates that Earth's orbital cycles contribute to similar periodicity in climatic variation — with the periods of the climatic cycles primarily ranging from 19,000 years to 1,200,000 years.
