What is the weighted average mass of all the know isotopes for an element?
Atomic Mass The technical answer would be average atomic mass Is the "atomic mass found on the periodic table.
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
The weighted average of the masses of all the naturally occurring isotopes of an element is the what?
Average atomic mass of the 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.
Atomic weight or atomic mass used in stoichiometric calculations.
What. (your question isn't even a complete sentence.)
The atomic weight of the element
The "atomic mass" or "atomic weight" number shown along with the element symbol in most periodic tables.
The Atomic mass of that element.
The weighted average for all isotopes that occur in nature for an element is its atomic weight listed on the periodic table of the elements.
Is An atom's atomic mass unit is equal to the weighted average of the masses of all the naturally occurring isotopes of that element?
Atomic unit mass (symbol u): 1/12 of the mass of an atom of carbon 12 in ground state and at rest (IUPAC definition). Sometimes used synonym: Dalton (Da) 1 u = 1, 660 538 …782.10-24 g
Average atomic mass
What is the term for the weighted average mass of all the naturally occurring isotopes of an element?
Pretty sure it is "Relative Atomic Mass" or "Mr"
The known weighted-average mass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________ *This is not the same as "all th…e known isotopes", because most elements have known isotopes that are not naturally occurring.
The "atomic mass". If the mass is expressed in units of grams as is usual, the mass would be called "gram atomic mass." Sometimes, especially several decades or more ago, the …value defined in the question was often called the "chemical atomic mass" of an element, which was contrasted with the "physical atomic mass" of a single isotope of the element.
