The atomic weight of the element (syn.: mass number).
base structure
atomic mass
For the chemical elements the correct expression is atomic weight.This value is the weighted average mass of the natural isotopes of this element.
Atomic masses are a weighted average of the naturally occurring isotopes.
Atomic mass is the number of protons and neutrons in an atom.
The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
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.
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.
The mean Atomic Mass.
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.
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.

The atomic weight of the element (syn.: mass number).
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
Atomic masses are a weighted average of the naturally occurring isotopes.
This is the weighted average neutron number for the naturally occurring isotopes of nickel, which has the atomic number 28 and the gram-atomic mass of 58.69. In an individual isotope, the neutron number is always the isotopic atomic mass number minus the atomic number, and the same principle applies to the weighted average neutron number for the naturally occurring isotopes of an element.
Atomic mass is the number of protons and neutrons in an atom.
