The mass of the naturally occurring mixture of isotopes for any element is called the atomic weight, whereas the mass of any individual isotope is simply called the isotopic mass.
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 atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
They are isotopes of that element, they have different neutron numbers.
The weighted average mass of a mixture of isotopes is calculated by multiplying the mass of each isotope by its natural abundance, and then summing these values together. This gives a more accurate representation of the overall mass of the isotopes in the mixture, taking into account their relative abundances.
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.
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.
It is called the Relative Atomic Mass.
The atomic mass is an average because most elements consist of a mixture of isotopes.
isotopes of the same element have different mass number
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 mass numbers of the isotopes of an element
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.
Isotopes of the same element have different numbers of neutrons and mass.
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
