Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a
Atomic Mass of First 30 Elements - Atomic Mass of Elements is Measured with the Help of its Unit - Atomic Mass Unit. One such Unit is Equal to One-Twelfth of the Mass of a Carbon-12 Atom Which is at Rest. Learn about Atomic Mass of First 30 Elements at B

choice of unit chemists. It’s equal to Avogadro’s number (6.02 X 1023) of atoms. For each element the atomic weight is on the periodic table right under the symbol of the element. The carbon atomic weight is 12 units of atomic mass (amu), so the weight of one mole is 12 grams....
To calculate the atomic mass of asingle atomof an element, add up the mass ofprotons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons. The...
mass and the atomic weight will be the same. Atomic mass and atomic weight may equal each other whenever you are working with a single isotope of an element, too. In this case, you use the atomic mass in calculations rather than the atomic weight of the element from the periodic table....

Atomic mass and atomic mass unit Each element in theperiodic tableconsists of atoms, and each atom has a unique atomic mass and unique atomic number. The atomic number refers to the number of protons in the atom's nucleus, while atomic mass reflects the sum of the number of protons and ...
