4.00 <--- that is the atomic mass of the atom
(in this case the helium atom)
.. as the mass of one mole of that particular (atomic) element.
it is the weighted average of the masses of an element's isotopes.
it is the weighted average of the masses of an element's isotopes.
The atomic weight (not mass) of a chemical element is calculated considering the percentage concentatration of natural isotopes and the atomic mass (not weight) of each isotope.
Magnesium is a meta element. Atomic mass of it is 24.
Atomic mass is the mass of 1 mole of the element. Atomic number is the number of protons the element has

AMU stands for atomic mass units; the number of units an element has is called its atomic mass. The atomic mass of carbon is exactly 12, by definition.
Element - Atomic Mass # Example: Carbon - 12
