Most of the atom's mass is concentrated in the nucleus.
The nucleus contains most of the mass of an atom. The nucleus in the atom is where the protons and neutrons co-exist. These are each about 2000 times the mass of an electron.
In the nucleus, rather than in the empty space between the electrons.
I think it might be the nucleus. but just double check
The Nucleus in the centre of the atom.
The rest of the atom is made up of nothing except from a few electrons, which have a much lower mass than either protons or neutrons.
Nucleus :) U welcom -.- B.A
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
Isotope.
Electrons orbit the Nucleus. the Nucleus contains protons and neutrons. The proton contains positive in charge (+) and Neutrons are neutral. (=) However, electrons are the ones with negative charge. (-)
The first two statement are false. The other one is true. There are electrons outside the nucleus, but they are much lighter than the particles in the nucleus.
Because more than 99 % from the mass of an atom is concentrated in the nucleus (protons + neutrons).
the nucleus
The nucleus contains the mass.
The nucleus, made up of protons and neutrons, contains most of an atom's mass.
Almost all of the volume of an atom has no mass.
Most of the mass in an atom is found in the nucleus, which contains the protons and neutrons.
No region has all the weight, but the vast majority of the mass of an atom is in the nucleus.
nucleons
The approximate mass of an atom that contains 10 protons and 11 neutrons is 21.
Most of the mass of an atom is found in the nucleus which contains the protons and neutrons.
Electron. Contains basicaly no mass what so ever.
Protons and neutrons. Virtually all of the atom's mass.
the nucleus is the center of an atom that contains the positively charged protons and the neutrally charged neutrons. It contains most of the mass of the atom.
