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.
because neutrons have the most mass in an atom and neutrons are located in the nucleus.
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.
The proton is located in the atom's nucleus, with the neutrons (if there are any).
Yes.
Rutherford
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.
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.
Most of the mass of an atom is located in the nucleus, which is made up of protons and neutrons. The nucleus is located at the center of the atom. Electrons, which have much less mass compared to protons and neutrons, orbit around the nucleus in electron clouds.
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.
99.9% of the mass of an atom is located in the nucleus
