What is atomic mass of an element?

A property closely related to an atom's mass number is its atomic mass. The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.

Regarding this, what does the atomic mass represent?

The mass of an atom, counted in u. “u” is 1/12 the mass of a carbon atom, roughly equal to the mass of a proton. Since the mass of a proton is about the same as the mass of a neutron, the atomic number also helps you remember an element's mass number (number of protons and neutrons, otherwise known as “nucleons”).

What does the average atomic mass of an element represent?

mass number: The total number of protons and neutrons in an atomic nucleus. natural abundance: The abundance of a particular isotope naturally found on the planet. average atomic mass: The mass calculated by summing the masses of an element's isotopes, each multiplied by its natural abundance on Earth.

What is the atomic mass of an element is equal to?

The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus. The AMU is used to express the relative masses of, and thereby differentiate between, various isotopes of elements.
