((16x40) +(18x60))/100 = 17.2
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
The characteristic of an element that represents the average mass of its isotopes is called the atomic mass. Atomic mass takes into account the abundance of each isotope of the element and is typically listed on the periodic table as a weighted average.
Isotopes have a different amount of Neutrons. The atomic mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
The answer is the atomic weight of the original element: It's the number on the top left of each element square of the Periodic Table.
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.
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.

This is the atomic weight.
the atomic mass
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
Isotopes have a different amount of Neutrons. The atomic mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
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.
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.
The atomic mass of an element is the weighted average of masses of the isotopes of the element, weighted in proportion to their abundance.
