the Atomic Mass
the average mass numbers of the isotopes of an element
Its the average of the weight of the different isotopes of that element.
the Atomic Mass
isotopes of the same element have different mass number
average atomis mass
Isotopes of the same element have different numbers of neutrons and mass.
They are isotopes of that element, they have different neutron numbers.
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.
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 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 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.
