What is the average atomic mass compared to atomic mass?

The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.


What is the difference between average atomic mass and atomic mass?

Average atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundances. Atomic mass refers to the mass of a single atom of a specific isotope of an element.


What is the difference between atomic mass and average atomic mass?

Atomic mass refers to the mass of an individual atom of a specific element, while average atomic mass is the weighted average of the masses of all the isotopes of an element, taking into account their relative abundance in nature. Average atomic mass is usually listed on the periodic table, while atomic mass is specific to a single isotope.
