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 element
ib - atomic mass of the isotope b x percent concentration of the isotope in the element
ic - 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 element
Make the sum: I = ia + ib + ic + ..... iz
The atomic weight of the element is: I/100 (the term weight is recommended by IUPAC in this case).
What else can I help you with?
How do the atomic number of the different isotopes an element compare?
The atomic number is the same for the all isotopes of a chemical element.
Does isotopes affect the physical properties of the element?
Isotopes contribute to the atomic weight of a chemical element.
What data must you know about the the isotopes of an element to calculate the atomic mass of an element?
Number of protons
Atoms of same chemical element that have different atomic mass are known as?
Isotopes. They differ in the number of neutrons in the nucleus.
Two isotopes of an element have different?
chemical properties. False. Isotopes of an element have the same chemical properties because they have the same number of protons and electrons, which determine the element's chemical behavior. The differences between isotopes lie in their nuclear properties, such as atomic mass and stability.

Do isotopes have the same A number?
The atomic number is the same for the isotopes of a chemical element.
What is an element that is the average mass of all the isotopes of that element?
This is a chemical element with a specific atomic weight.
How could physicists propose an element to put in a periodic table if sometimes like uranium have different atomic number and atomic mass?
The atomic number of the isotopes of an chemical element is the same; only the atomic mass of the isotopes is different. Also the isotopes of an element have the same chemical and physical properties (of course with some approximation).
What information about an element's isotopes is needed to calculate that element's average atomic mass?
the atomic number of each isotope-apex;)
How is the atomic mass of an element calculate?
By taking the wieghted averages of naturally occurring isotopes of that element. :)

Can two atoms of same element ever have different atomic numbers?
The atomic number is identical for all the isotopes of the same chemical element.
How do you calculate the atomic mass of an element containing a mixtures of isotopes?
weighted average of the various iisotopes
