8. On most periodic tables a single atomic mass is listed instead of the mass numbers for all the stable isotopes. How is this mass related to the different isotopes?

In a normal Periodic Table, the molar mass of a given element, is made up of multiplying the mass of a given isotope of that element, with the abundance of that given isotope in percent.
For example, Say for the element X, you know that it has two isotopes, X12 and X13. X12 has a molar mass of 12 g/mol, and you know that of all the X molecules in the world, X12 is found 95% of the time, X13 has a molar mass of 13g/mol, yet its abundence is only 5%. Therefore average molar mass for element X is calculated as such,
(12 * .95)+(13*.05) = 12.05 g/mol.
hope that helps.

What same mass numbers do isotopes have?
Mass numbers of isotopes are different.
What does isotopes?
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
How are all the isotopes of an element simular and how are they different?
Atoms of all isotopes of a single element have the same number of protons in their nuclei but have different numbers of neutrons if they have different mass numbers.
How are isotopes different than naturally occurring elements?
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
What same mass numbers do isotopes have?
Mass numbers of isotopes are different.
Isotopes of an element have a different number of?
neutrons
What Have different isotopes of the same element?
Isotopes of the same element have different numbers of neutrons and mass.
What does isotopes have to do with mass numbers?
isotopes of the same element have different mass number
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Define the term isotope explain how two isotopes of an element are different?
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^
What does isotopes?
All atoms of an element contain the same number of electrons and protons but they can have different numbers of neutrons. Atoms with different numbers of neutrons are isotopes.
Isotopes of uncharged elements have different numbers of?
Isotopes differ in the number of neutrons they possess.
What are atoms containing the same numbers of protons and different numbers of neutrons are?
These atoms are called isotopes.
Why does bromine have different mass numbers?
Bromine isotopes have different mass numbers because their atoms have different numbers of neutrons.
How are all the isotopes of an element simular and how are they different?
Atoms of all isotopes of a single element have the same number of protons in their nuclei but have different numbers of neutrons if they have different mass numbers.
What isotopes of uncharded elements have different numbers?
The atomic number of the isotopes of an element is identical; the mass number is different.
