The nucleolus.

The PROTONS and NEUTRONS in the nucleus of an atom make nearly all the mass of an atom.
By definition a proton has mass of '1'
A neutron has a mass of '1'
However an electron has a mass o 1/1860 of a proton.
So as an example, taking carbon .
It has a mass of '12' , composed of 6 x 1 protons + 6 x 1 neutrons. The '6' electrons only have a comparable mass of 6/1860 = 1/310.

What makes up nearly all of the atoms's mass?
The sum of all Protons and Neutrons.
What is nearly all of an atoms mass made up of?
Nearly all of an atom and mass is made up of protons and neutrons.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
What makes up nearly all of atom mass?

What makes up nearly all of the atom's mass?

Where does majority of a atoms mass come from?
Very nearly all of the mass of an atom is found in the nucleus in the form of Protons and Neutrons. Electrons and "binding energy" contribute a tiny amount of additional mass.
Is it true that not all kinds of matter have mass?
No. Everything has mass. Atoms have mass, Everything has atoms. :) Atomic Mass Number for example. :)
John Dalton concluded that all the atoms of a single what have the same mass?
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
