What part of the atom has the greatest mass?

Answer 1

The heaviest part of an atom is its nucleus which contains the atoms proton(s), and possibly nuetrons. Protons are approximately 10000 times heavier than the electrons in an atom which occupy the electron cloud surrounding the atom.

Answer 2

The nuclease is the heaviest part of the atom being thousands of times the weight of the rest of it. In the nucleus there are two kinds of sub atomic particles, the protons and the neutrons. The neutrons are very very slightly more massive than the protons.

Answer 3

This depends on whether you are referring to the atom as a whole or if you mean what gives the most mass in the nucleus (which is where the most weight is in an atom). The weight of the nucleus or the center of the atom is the number of neutrons plus the number of protons, assuming we calculate by the relative mass of both particles, which is 1 Atomic Mass unit (amu).

Atomic mass = # neutrons + # protons

The neutron has a relative mass of 1 amu, yet its actual mass is about 1.675 x 10-24 grams.

The proton has a relative mass of 1 amu, yet its actual mass is about 1.673 x 10-24 grams.

The electron is not calculated in the atomic mass (not part of the nucleus), as it has a relative mass of 0 atomic mass units (amu), although its actual mass is actually about 9.110 x 10-28 grams.

The particle that weighs the most in an atom is the neutron, although the atomic mass as stated above is the sum of how many neutrons and protons are located in the nucleus.

Answer 4

protons is part of the atom that has the most mass, because proton is possitive and has the most mass

Answer 5

the electron with 9.1093*10-28 compaired to a neutron ( 1.6749*10-24 ) and to a protron with ( 1.6726*10-24 )
