The protons and neutrons found in the nucleus are responsible for the majority of the atom mass while the much smaller electrons orbit the nucleus.

How is a molecule diffent from a atom?
A molecule contains more than one atom.
Where is almost all of the mass in an atom is located?
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.
What was James Chadwick's contribution to the atom?
AnswerJames Chadwick was the first man to discover the neutron-the neutrally charged particle of the nucleus (which also contains protons, positively charged particles). Electrons whizz around the nucleus (which is the heaviest part by far of the atom) on "orbits".
How do we find the mass of an atom?
A mass spectrometer measures atomic mass by removing one or more electrons from an atom. The spectrometer then sends the atom through a magnetic field. Because of the missing electrons, the atom has more protons than electrons, resulting in a positive charge. The magnetic field bends the path of the positively charged atom as it moves through the field. The amount of bending depends on the atom's mass. The atomic mass of the atom can be calculated from the magnitude of the bend.
What is the number of atomic mass in a atom?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
Does water have more hydrogen or oxygen in it?
By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
Which body accounts for more than 99 percent of the mass of the solar system?
The sun contains over 99% of the mass of the solar system. The numbers reveal that the sun actually contains over 99.8% of the mass of the solar system.

What is the mass and volume of the nucleus?
If you mean the nucleus of an atom, different atom have different masses - an uranium atom has more than 200 times the mass of a hydrogen-1 atom (and most of that mass is in the nucleus).
Most of the mass of the atom is where?
More then 99% of an atoms mass is in the nucleus.

What are the differences between a proton and an electron?
a proton is a part of the atom, more specifically the nucleus (which also contains neutrons) and the electron is an even smaller particle that rotates around the nucleus of the atom and has a mass so minuscule even to an atom it is generally given the weight of zero.
Why the nucleus is very dense?
Because more than 99 % from the mass of an atom is concentrated in the nucleus (protons + neutrons).
Is Most of the mass in an atom is in electrons?
the mass of electrons is negligble the pe rcentage of an atom's mass comes from its protons and neutrons
