Yes, most of the mass of an atom is found in the nucleus. If you consider that a proton is over 1800 times more massive than an electron, it might come into focus. The neutron is just a tiny bit heavier than that proton. A single nucleon, which is the term we give a proton or neutron residing in the nucleus of an atom, will far, far outweigh all of the electrons that could possibly be around it. And by a factor in excess of 103, too. No, there isn't a lot of mass in the electron cloud as a whole.
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 is comprised of protons, neutrons, and electrons. The electrons take up the most space as they orbit the nucleus. But nearly all of the mass of the atom is found in the nucleus of the protons and neutrons.
Nuetrons are found in the center of an atom which is called the nucleus.
When calculating the mass of an atom, you add the mass of the protons and the neutrons. This is the nucleus of the atom. The electrons are small enough to be ignored except in the most delicate calculations.
Neutrons and protons are located in the nucleus of an atom. The nucleus is the central part of an atom that contains most of its mass and is surrounded by electrons in the electron cloud.
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.

In 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.

Essentially all of the atom's mass is in the nucleus. In the lightest atom, that of hydrogen, it's about 99.95 percent. In the heaviest naturally occurring atom, that of Uranium238, it's about 99.979 percent.
