The known weighted-average
mass of all the naturally occurring* isotopes for an element is the atomic mass of the element.

Atoms of the same element with different mass numbers are known as?
Isotopes.
When atoms of the same element have different mass numbers they are known as?
isotopes
What Is the weighted average of all of the isotopes of an element.?
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.
What is the difference between atomic mass number and atomic number?
Atomic mass number is the average atomic mass for that element, which is : All the isotopes' masses known for that element averaged up. Atomic number is the element's "identity", the number of protons the element and all its isotopes have. All the isotopes of a given element will have different number of electrons and neutrons, but the protons of the element never will change.
What does isotopes have to do with mass numbers?
isotopes of the same element have different mass number
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
What is the weighed-average mass of all the known isotopes for an element called?
Average Atomic Mass, or Atomic Weight of an element (the one shown on the Periodic table).
How is average atomic mass determined from isotopic masses?
The atomic mass that you see on the periodic table is an average mass taken from all of the element's known isotopes. Simply find the average of all of the masses of the isotopes of an element.
How do you distinguish isotopes by mass spectrometer?
Isotopes (of the same element) have different mass, this is measured by the mass spectrometer
