D
Neutron
Verified step by step guidance1
Understand the structure of an atom: An atom consists of a nucleus and an electron cloud. The nucleus contains protons and neutrons, while electrons orbit around the nucleus.
Identify the subatomic particles: Atoms are made up of three main subatomic particles: protons, neutrons, and electrons.
Determine the location of each particle: Protons and neutrons are located in the nucleus of an atom, while electrons are found in the electron cloud surrounding the nucleus.
Focus on the question: The problem asks which subatomic particle is found in the nucleus of all atoms. This means we are looking for a particle that is always present in the nucleus.
Conclude based on the information: Since protons are positively charged particles found in the nucleus of every atom, they are the subatomic particles that fit the criteria of being in the nucleus of all atoms.
