What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
Which is a factor in determining the average atomic mass of an element?
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes, the atomic mass of an element takes into account the relative abundance of each isotope of that element. This is because atomic mass is the weighted average of the masses of all isotopes of an element based on their natural abundance.
What is necessary to calculate the atomic mass of an element is?
You need to know the atomic # or the masses of each isotope of the element.
How do you calculate the atomic weight of a chemical element that has two or more isotopes?
To calculate the atomic weight of an element with multiple isotopes, you multiply the mass of each isotope by its relative abundance (as a decimal), then sum the products. The result is the atomic weight of the element, which is a weighted average of the masses of its isotopes based on their abundance in nature.

How do you find the atomic number of an isotope?
The atomic number of an isotope is always identical to every other isotope, otherwise, it would form a separate element.

An isotope shares the atomic number with its element atom How does it differ from the element atom?
An isotope shares the atomic number with its element atom. How does it differ from the element atom?
Why need to know the percentage of each isotope of an element to determine the atomic mass?
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
What does it mean for an isotpe to be radioactive?
An isotope is radioactive if it undergoes spontaneous decay, emitting particles or radiation in the process. This decay results in the transformation of the atomic nucleus into a different element or a different isotope of the same element.
What element has the atomic mass of 22?
An isotope of Neon. This isotope accounts for between a fifth and a quarter of the element.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes, the atomic mass of an element takes into account the relative abundance of each isotope of that element. This is because atomic mass is the weighted average of the masses of all isotopes of an element based on their natural abundance.

What are atoms of an element have the same atomic number but a different atomic mass?
isotope

When an isotope undergoes beta decay which of the following does not change A the atomic number B the name of the element C the mass number D all of these change?
B. The name of the element does not change during beta decay. The atomic number (Z) increases by one unit as a neutron is converted to a proton, while the mass number (A) remains the same.
