The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.
The middle part of the atom is called the nucleus, which is composed of protons and neutrons. Protons have a positive charge, while neutrons have no charge. The nucleus makes up the majority of the atom's mass.
The nucleolus.
The nucleus is the part of the atom made up of protons and neutrons, and it contains nearly all of the atom's mass. Electrons, which have much lesser mass, orbit around the nucleus.
This would be the NUCLEUS.
Empty space makes up most of the volume of an atom. The nucleus (protons and neutrons) make up most of the mass.
The smallest part of an atom would be a quark. Quarks are either up or down quarks, and have virtually no mass. Neutrinos have even less mass, but are not part of an atom.
The nucleus makes up most of the mass and the other things in the atom make up the rest.
The center solid part of an atom is called the nucleus. It contains protons and neutrons, which are held together by strong nuclear forces. The nucleus makes up most of the atom's mass and is surrounded by a cloud of electrons.
