The Atomic Mass of an element is the average of all the isotopes of that element that exist on this earth, either naturally or artificially.
An isotope is an atom that differs in the number of neutrons that it would normally have (which is usually the same as the number of protons it has, except in the case of hydrogen).

What is the average mass of the isotope of an element?
the average mass numbers of the isotopes of an element
What is weighted average mass of an element isotopes?
average atomis mass
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
How does the average atomic mass of an element differ from the mass of an individual atom of the same element?
The average atomic mass takes into account the different isotopes of an element and their relative abundance, while the mass of an individual atom is specific to that particular isotope. The average atomic mass is a weighted average based on all isotopes present in a sample, providing a more accurate representation of the element's mass in nature.
How is the molar mass of an element related to average atomic mass?
The molar mass of an element is the mass of one mole of atoms in that element. It is directly related to the average atomic mass, which is the weighted average of the masses of all isotopes of that element based on their natural abundance. The molar mass is usually very close to the average atomic mass of the element.
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.
What is the average of the mass numbers of isotopes of an element?
the atomic mass
What is the weighed-average mass of all the known isotopes for an element called?
The weighted-average mass of all the known isotopes for an element is called the atomic weight or atomic mass. It is calculated by taking into account the abundance of each isotope and its mass to determine the average mass of all isotopes present in nature for that element.
What is the molar mass of an element with an average atomic mass of 9.012u?
9.012 grams, if the formula weight of the element is a single atom. This number would be multiplied by the subscript in the formula of a polyatomic element form.
Why is there an average atomic mass?
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
What does the atomic mass tell you about the atom?
The Atomic Mass of an element tells you the average mass of an atom in the element.
Why is the atomic mass an average?
Because there can be many different forms of that element. So they they find the mass of all the forms of that element and make is an average.
