Tungsten is a non meta element. Atomic Mass of it is 74. Atomic number of it is 183.
The mass of one tungsten atom is approximately 183.84 atomic mass units (amu).
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.
The atomic weight of protactinium is 231,03588.
The atomic mass of an atom is the sum of the number of protons and neutrons in the nucleus. It is generally expressed in atomic mass units (amu). The atomic mass is important for determining the overall mass of an atom and for calculating molar masses in chemical reactions.
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.

The atomic mass number of an atom, if the atom's mass number is approximately equal to 0.33 that of carbon-12, would be 4. If the question is about actual masses rather than mass numbers, the mass of a helium-4 atom is about 4.00260 atomic mass units, while the mass of a carbon-12 atom is, by definition, exactly 12.000..... atomic mass units.
Lead is a non element. Atomic mass of it is 12.
The atomic mass gives the mass of the atom. It is one of the physical property of the atom.
