Which set correctly lists the three main subatomic particles in an atom?
A
Protons, neutrons, and electrons
B
Protons, isotopes, and electrons
C
Protons, electrons, and ions
D
Neutrons, molecules, and electrons
Verified step by step guidance1
Understand that an atom is composed of smaller particles called subatomic particles, which determine its properties and behavior.
Recall the three main subatomic particles: protons, neutrons, and electrons. Protons carry a positive charge, neutrons have no charge (neutral), and electrons carry a negative charge.
Recognize that isotopes are variations of atoms with different numbers of neutrons, ions are charged atoms or molecules, and molecules are groups of atoms bonded together; these are not subatomic particles.
Compare each option to the correct list of subatomic particles: protons, neutrons, and electrons.
Identify the set that exactly matches the three main subatomic particles without including other terms like isotopes, ions, or molecules.
