Ernest Rutherford discovered that most of the atom's mass is in the nucleus in 1911. When Rutherford fired alpha particles at a thin layer of gold foil he found that approximately 1 in 8000 particles were deflected. This lead to his theory that most of the atom was empty space besides a massive nucleus.
Rutherford said most of an atoms mass is its nucleus in 1911

The most mass of an atom is found in the nucleus.
If you mean the nucleus of an atom, different atom have different masses - an uranium atom has more than 200 times the mass of a hydrogen-1 atom (and most of that mass is in the nucleus).
Nucleus
In the nucleus of the atom, along with neutrons. The electrons are found around the nucleus. If the atom was the size of a Baseball stadium, the nucleus would be the size of a baseball! Most of the space in an atom is taken up by the electron cloud which surrounds the nucleus. That is why atoms are actually mostly empty space.
The nucleus is pretty much light. But it contains the most mass of an atom.
More then 99% of an atoms mass is in the nucleus.
The mass of an atom is concentrated in the nucleus (protons+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.
This is the nucleus, containing protons and neutrons.

The nucleus of an atom represents most of an atom's mass.
The most mass of an atom is found in the nucleus.
Most of the mass of an atom is within the nucleus of the atom. The nucleus is composed of protons and Neutrons, whilst the outer orbits are only covered by electrons. Just the protons in the nucleus weight upwards of 1800X more than the electrons outside.
It is the nucleus. Mass of electrons is too small
