The mass of the nucleus is 2.34348 * 10^(-26) kilogram. The mass of a neutron is always greater than a proton as basically speaking a neutron is composed of a proton and electron and other subatomic particles.

Yes, the nucleus accounts for almost all the mass of an atom. It contains protons and neutrons, which have most of the atom's mass. Electrons, which orbit the nucleus, have very little mass in comparison.

It's changes from every element to element.

The Nucleus composed from protons and neutrons. In the basic form, in Nucleus, the number of protons equal to the number of neutrons.

The mass of proton is 1.672x10^-27 kg.

The mass of neutrons is 1.674x10^-27 kg.

The nucleus of an atom is made up of protons and neutrons. The number of which varies according to the element.

The more more of these particles there are then the heavier the nucleus will be.

The mass of the neutron is 938,272 013 MeV/c2. There are a number of mesons, and their masses vary according to which one is under inspection. The neutron may be a few hundred to a few thousand times as massive as a given meson, depending on which one it is compared to. Use the link below and check the data table to make comparisons and determine how much heavier the neutron is than a given meson.

. In the nuecleous of an atom all the Atomic Mass ( known as a.m.u - atomic mass unit) is found inside the nuecleous. One single proton is 1.0 a.m.u ( or atomic mass unit) and one neutron is 1.0 a.m.u. Electrons have no atomic mass due to the fact that they are constantly moving and anyway would have very little mass.

Very nearly all of it.

The most complex atom that occurs in nature has something like 90 to 95 electrons,

but every single proton or neutron in the nucleus of any atom has the mass of

more than 1,800 electrons.

This depends on the half-life of the atom


Where can the most mass be found in an 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.

What part of an atom carries most of its mass?

The vast majority of an atom's mass is within the nucleus; the electrons orbiting the nucleus, which do contain the same amount of charge as the nucleus(albeit negative), have virtually no mass when compared to the nucleus. In fact many scientific disciplines disregard the mass of electrons altogether.


What does nucleus of an atom have?

The nucleus of an atom contain protons and neutrons; protons and neutrons contain quarks and gluons.


In the atom nearly all the mass is found in the what?

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.
