In the definition of relative Atomic Mass, the term "weighted" refers to the consideration of the abundance of each isotope of an element when calculating its average atomic mass. Instead of simply averaging the masses of all isotopes, the relative atomic mass is determined by multiplying the mass of each isotope by its relative abundance, then summing these values and dividing by the total abundance. This ensures that isotopes that are more prevalent in nature have a greater influence on the final average atomic mass.

What is the difference between mass number relative atomic mass and average atomic mass?
The mass number is the total number of protons and neutrons in an atom's nucleus. Relative atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundance. Average atomic mass is the weighted average mass of an element's isotopes in a given sample, considering their abundance in that sample.
What is often used in place of atomic weights?
Relative atomic masses are often used in place of atomic weights. They represent the weighted average of the masses of the isotopes of an element relative to the mass of a carbon-12 atom.
Is the atomic mass on the bottom or top?
At the bottom, the atomic number is at the top.
Which best describes the definition of the atomic mass of an element?
it is the weighted average of the masses of an element's isotopes.
Which best describes the definition for the atomic mass of an element?
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
How is the atomic mass for chlorine related to isotopes for that atom?
The average atomic mass is weighted by the most common isotopes and their relative abundance.

How is the atomic mass of an element determined?
The atomic mass of an element is determined by calculating the weighted average of the masses of its isotopes, taking into account their relative abundance.
Why atomic mass of atom is defined as relative atomic mass?
It is calculated as the ratio of the mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. In fact, the weighted average of the mass of an atom of an element - weighted according to its isotopic abundance.
