in the nucleus
It is the nucleus. Mass of electrons is too small
99.9% of the mass of an atom is located in the nucleus
virtually all the mass in concentrated in the nucleus of the atom, as the electron's mass is so small, it is negligible.

in the nucleus of the atom
The mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The nucleus is extremely small compared to the overall size of the atom, but it contains almost all of the atom's mass. Electrons, which are much smaller in mass, orbit around the nucleus.
The mass of an atom is concentrated in the nucleus (protons+neutrons).
The mass of an atom is concentrated in the nucleus, which is made up of protons and neutrons.
The mass of an atom is concentrated in the nucleus. Protons are a part of the nucleus, but not the entire thing. Neutrons are also in the nucleus and have nearly the same mass as protons.
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.
An atom does have mass. The mass of an atom is primarily concentrated in its nucleus, which is made up of protons and neutrons. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
The mass of an atom is concentrated within its nucleus, which contains protons and neutrons. The electrons, which have negligible mass compared to protons and neutrons, orbit around the nucleus in specific energy levels.
