The nucleus.

Inside the nucleus.
Protons and neutrons, which are found in an atom's nucleus, account for most of an atom's mass. Electrons, which orbit the nucleus, have much less mass compared to protons and neutrons.
More then 99% of an atoms mass is in the nucleus.
The nucleus makes up nearly all of the mass of an atom, with over 99% of its mass concentrated in the nucleus. Within the nucleus, most of the mass is found in the protons and neutrons, while the electrons surrounding the nucleus contribute very little to the overall mass.
The mass of an atom is concentrated in the nucleus (protons+neutrons).
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
The sum of all Protons and Neutrons.
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.
