When an isotope undergoes alpha decay which of the following change A The name of the element B The atomic number C The mass number D All of these change?
The answer is D. All of these change.
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)
What is the atomic number of isotope?
Well all Isotopes have the same atomic number so if you have the element the atomic number of an element with that same isotope is that same atomic number.
Does the atomic mass of an element depend upon the relative abundance of each isotope of the element?
Yes. The gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that 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

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?
What is the atomic number of isotope?
Well all Isotopes have the same atomic number so if you have the element the atomic number of an element with that same isotope is that same atomic number.
If an isotope undergoes beta emission?
If a radioactive isotope undergoes beta emission, a. The atomic number changes B. the number of neutrons remains constant c. The mass number changes d. The todo isotope loses and electron
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 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 gram atomic mass of each element is the sum of the products of each stable isotope's isotopic fraction multiplied by the mass of that 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
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 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.
How do you calculate the atomic weight of a chemical element that has two or more isotopes?
Calculation of the atomic weight of an element having many isotopes:ia - atomic mass of the isotope a x percent concentration of the isotope in the elementib - atomic mass of the isotope b x percent concentration of the isotope in the elementic - atomic mass of the isotope c x percent concentration of the isotope in the element...........................................................................................................................iz - mass of the isotope z x percent concentration of the isotope in the elementMake the sum: I = ia + ib + ic + ..... izThe atomic weight of the element is: I/100 (the term weight is recommended by IUPAC in this case).
