The majority of an atom's mass is concentrated in its nucleus, which is composed of protons and neutrons. Protons have a positive charge and neutrons have no charge, together making up nearly all of the atom's mass. In contrast, the electrons, which orbit the nucleus, contribute very little to the overall mass of the atom. Thus, while the nucleus is small relative to the entire atom, it contains the vast majority of its mass.
mas mas
A. It is the most massive part of the atom. The nucleus, composed of protons and neutrons, contains the majority of an atom's mass, while electrons, which are negatively charged, orbit around the nucleus. Thus, options B, C, and D are incorrect.
Space
Protons are located in the nucleus of an atom, which is the central core that also contains neutrons. Together, protons and neutrons make up the majority of an atom's mass. Protons carry a positive charge, while neutrons are neutral. Electrons, which are negatively charged, orbit the nucleus in electron shells.
The nucleus contains the mass.
mas mas
Neutrons are located in the nucleus of an atom, along with protons. Together, neutrons and protons make up the majority of an atom's mass. Electrons, which are negatively charged particles, orbit around the nucleus.
The majority of an atom's mass is found in the nucleus, which contains protons and neutrons. Electrons, which are much smaller in mass, are located in the electron cloud outside the nucleus.

The majority of an atom's mass is found in its nucleus, which is located at the center of the atom. The nucleus is composed of protons and neutrons, which are much more massive than the electrons that orbit the nucleus.

The great majority of the mass of an atom is found in the nucleus, where protons and neutrons are located. The nucleus is incredibly dense and accounts for almost all of the atom's mass, while electrons, which are much smaller and lighter, contribute very little to the overall mass of the atom.
The proton is located in the atom's nucleus, with the neutrons (if there are any).
An atom's mass is concentrated in its nucleus, which is located in the center of the atom. Protons and neutrons within the nucleus are responsible for its mass; the electrons, which are located outside of the nucleus, don't contribute to the mass of the atom.
