What Is the weighted average of all of the isotopes of an element.?
The answer is the atomic weight of the original element: It's the number on the top left of each element square of the Periodic Table.
How many naturally occurring isotopes are in technetium?
Technetium is a man made element.
Why does the mass number not appear on the periodic table?
Mass number is a property specific to a particular isotope or nuclide of an element, while the usual periodic table include average properties for all the stable, naturally occurring isotopes of each element.
How are isotopes different than naturally occurring elements?
Isotopes of an element have different masses because their nuclei have different numbers of neutrons.
What is the isotope number used for on the periodic table?
There is not an isotope number on the Periodic Table of Elements. There is an atomic number (# of protons) and the average atomic mass. The average atomic mass is the weighted average of all the naturally occurring isotopes for each element. This number is not a whole number, because it is an average of all the isotopes for a particular element.
What is the weighted-average mass of all the known isotopes for an element?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The atomic weight that is listed on the periodic table for each element is the weighted average of the atomic masses of an element's naturally occurring isotopes. So you are describing atomic weight as it is used on the periodic table.
How are isotopes placed in the periodic table?
Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).
What is the average of all the naturally occurring isotopes of a particular element?
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
The average mass of all the known isotopes of an element is what?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
Is the weight average mass of all the known isotopes for an element?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
Is radon the element naturally occurring?
The radon isotopes 222Rn and 220Rn are natural isotopes.
Is gallium a naturally occurring isotopes?
No. Gallium is an element. The element Gallium has two naturally occuring stable isotopes (69Ga and 71Ga) and abpout 29 unstable isotopes.
Is tin an isotope?
Tin is an element with ten naturally occurring isotopes.
What Is the weighted average of all of the isotopes of an element.?
The answer is the atomic weight of the original element: It's the number on the top left of each element square of the Periodic Table.
What are atomic mass?
Atomic mass is the weighted average of all naturally occurring isotopes. Or in other words, the mass of an element. It's located under the element symbol on the periodic table.
How is the atomic mass of an element calculate?
By taking the wieghted averages of naturally occurring isotopes of that element. :)
