No region has all the weight, but the vast majority of the mass of an atom is in the nucleus.
None Even electrons have weight
Almost all of the volume of an atom has no mass.
The nucleus is the region of the atom where most of the atom's positive charge and almost all of its mass is concentrated. It contains protons and neutrons tightly packed together. The electrons orbit around the nucleus in different energy levels.
Helium atom has 2 protons and 2 neutrons (that accounts for its atomic weight). The atomic weight of helium is 4.00260
That region is called the nucleus of the atom.

the price is your mama lol pwned
Finding out how many neutrons are in a atom is easy. All you have to do is find the element's atomic number and atomic weight.
The region of an atom in which the electrons move is called the electron shell, or electron cloud.
The weight of an atom is primarily determined by the total number of protons and neutrons in its nucleus. Electrons, which have negligible mass, also contribute to the atom's weight but to a much smaller extent.
