If 40 percent of the isotopes of an element have a mass of 16 atomic mass and 60 percent of the isotopes have a mass of 18 atomic mass what is the average atomic mass?
((16x40) +(18x60))/100 = 17.2
How the atomic mass of an element is affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
Atomic mass differnet from the atomic mass number why is that?
The atomic mass is an average, allowing for the relative abundances of different isotopes.
What is clorine's atomic mass number?
35.4527
What is the same in isotopes?
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
Clorine 35 and clorine 37 are examples of?

How is the atomic mass for chlorine related to isotopes for that atom?
The average atomic mass is weighted by the most common isotopes and their relative abundance.
How is the atomic mass of an element affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.

Do isotopes have the same atomic number and the same atomic mass?
No: They have the same atomic number but not the same atomic mass.
Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
