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.
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).
Are the mass number is an average of the masses of all naturally occurring isotopes of an element?
Yes they do.
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 a weighted average of the masses of all of the naturally occurring isotopes of an element?
The mean Atomic Mass.
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.
Can explain in terms of isotopes why the relative atomic mass of atomic number 17 is not a whole number?
Mass number is the average of all the naturally occurring isotopes of that element. When calculated, this average is not a whole number.
The atomic mass of an element is defined as the weighted average mass of that element's?
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
What is the weighted average of the masses of all naturally occurring isotopes of an element?
The atomic weight of the element (syn.: mass number).
What is the mass number of sliver?
Mass number is a property of isotopes, not elements themselves. Naturally occurring silver is a mixture of isotopes with mass numbers 107 and 109, with an average atomic mass of 107.9.
