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.
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
What do you mean? Atomic mass of an atom is the weighted average mass of all the naturally occurring isotopes of that element, measured in amu (=atomic mass unit). I do not know how do you want to call it, it is just atomic mass, average atomic mass, mass of an atom, atom's mass...
No! The mass of one atom of each element increases as you move down and to the right on a periodic table. The mass of an atom of a particular element is called its atomic mass.
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
Neutrons can be removed or added to change the atomic mass of an atom; a atom with the same amount of protons but different amounts of neutrons are called isotopes.(Taking or removing protons would change the type of atom and electrons do not have sufficient mass to change the atomic mass.)
Isotope.
The most mass of an atom is found in the nucleus.

The sum of protons and neutrons in an atom is called mass number.

If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.
