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.
Atomic mass and mass of an atom are somehow different from one another. Atomic mass of carbon will be 12. But mass of one carbon atom will be 1.992 x 10-23 g. As we say atomic mass as 12, it means that it will be 12 times as that of hydrogen atomic mass. If we say 12 g of carbon then it will be considered as gram atomic mass of carbon. Each gram atomic mass of an element will have 6.023 x 1023 number of atoms. 6.023 x 1023 is known as Avogadro's number. Gram atomic mass is also termed as one gram mole. So 6.023 x 1023 atoms weigh 12 g. Then one atom's mass ie mass of one atom will be 12/ 6.023 x 1023 = 1.9923626 x 10-23 g.
