By far it is in the nucleus. Neutrons are very slightly more massive than protons, but not all atoms have neutrons. All atoms will have at least one proton. Protons and neutrons are both much, much more massive than electrons. Relatively speaking.
An atom is made up of protons and neutrons in a nucleus, surrounded by smaller electrons. It takes 1830 electrons to make up the mass of one proton, so the majority of the mass is in the nucleus.
Almost the entire mass of an atom is located in the nucleus.

It is the nucleus
Nucleus
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.

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.
The particles are protons, neutrons, and the nucleus inside of the atom Nice helping u >_<
because neutrons have the most mass in an atom and neutrons are located in the nucleus.

Rutherford discovered in the early 1900s that most of an atom's mass is located in its nucleus.
The most mass of a atom is located in the nucleus, where the protons and the neutrons are located.
Yes.

The nucleus.
Approximately all of the atom's mass is in the nucleus. The electrons contribute almost zero.No atom has more than 100 electrons, but eachproton or neutron in the nucleushas the mass of more than 1,800 electrons.
in the centre within nucleus where protons and neutrons are located.protons and neutrons have atomic mass of 1 u each while electrons revolving around have mass=0u[almost negligible]. so most of the mass is located in centre of an atom.
99.9% of the mass of an atom is located in the nucleus
