The average Atomic Mass of an element is the weighted average of the masses of its isotopes, based on their abundance in nature. It is calculated by multiplying the mass of each isotope by its relative abundance, then summing these values together. This average mass is given on the Periodic Table.

Which best describes the definition for the atomic mass of the element?
it is the weighted average of the masses of an element's isotopes.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
In each element square on the periodic table there is a number that has a decimal point in it what does this number represent?
The number with a decimal point in each element square on the periodic table represents the average atomic mass of that element. It takes into account the mass of different isotopes of the element and their relative abundance in nature.
Isotopes are atoms of the same element that different numbers of?
Isotopes are atoms of the same element that have different numbers of neutrons in their nuclei. This leads to variations in atomic mass for isotopes of the same element.
Which two notations represent atoms that are isotopes of the same element?
Isotopes of the same element have the same number of protons but different numbers of neutrons. Thus, two notations representing isotopes of the same element would differ only in the mass number, for example, carbon-12 (12C) and carbon-14 (14C) both represent isotopes of carbon.
What is the average mass of the isotope of an element?
the average mass numbers of the isotopes of an element
Why are the atomic mass numbers of an element not hole numbers?
Its the average of the weight of the different isotopes of that element.
How is the atomic mass of an element is affected by the distribution of its isotopes in nature?
The atomic mass of an element is affected by the distribution of its isotopes in nature because the atomic mass is a weighted average of the masses of all naturally occurring isotopes, taking into account their abundance. Isotopes with higher abundance will have a greater influence on the overall atomic mass of the element compared to isotopes with lower abundance.
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.
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.
What is weighted average mass of an element isotopes?
average atomis mass
What Have different isotopes of the same element?
Isotopes of the same element have different numbers of neutrons and mass.
Which best describes the definition for the atomic mass of the element?
it is the weighted average of the masses of an element's isotopes.
What does isotopes have to do with mass numbers?
isotopes of the same element have different mass number
What is the average of the mass numbers of isotopes of an element?
the atomic mass
What is it called when you have the same element but different mass number?
They are isotopes of that element, they have different neutron numbers.
What is the average mass of the mixture of an elements isotopes?
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
