Protons and neutrons, because the mass of electrons is very insignificant - 1/1840 in relation to protons and neutrons, which are both 1 each.
What else can I help you with?
What is the part of the atom that makes up the mass of the atom?
the nucleus of the atom
What parts of an atom makes up all the mass of an atom?
The nucleus is the part of an atom that contains practically all its mass. In the nucleus, you can find the proton and neutron. The number of electrons, which move about the nucleus, is equal to the number of protons.
What makes up most of the mass of Atom?
protons and neutrons make up most of the mass in an atom
What makes up most of the mass of an atom?
protons and neutrons make up most of the mass in an atom
What part of an atom makes up the mass of an atom?
the nucleus
What makes up nearly of the atom's mass?
The nucleolus.
What makes up most of the volume of an atom.?
Empty space makes up most of the volume of an atom. The nucleus (protons and neutrons) make up most of the mass.
What makes up of the atoms?
The nucleus makes up most of the mass and the other things in the atom make up the rest.
What sub atomic particles makes up mass of an atom?
Protons and neutrons
Which subatomic particles makes up most of the mass off the atom?
The major contribution to the mass of an atom is from protons and neutrons; electrons have a known but negligible mass.
How big are the parts of the atom compared to the whole atom?
The nucleus of an atom is very small compared to the size of the whole atom. The nucleus makes up only a tiny fraction of the atom's total volume, while the rest of the atom (which is mostly empty space) is occupied by the electron cloud.
What parts of an atom make up the atom's atomic mass?
An atom's mass is located entirely in the nucleus. In the nucleus, there are protons and neutrons. Electrons are located outside of the nucleus, but because the mass of an electron is so insignificantly small, it's not counted when determining the total mass.
