Why do elements have a listed average atomic mass and not just atomic mass?
Because most naturally occurring elements are a mixture of isotopes, each having a different atomic mass. These individual isotopic atomic masses must be combined accounting for the amount of each isotope of the element is present to get a weighted average atomic mass.
How is the mass number different from the average atomic mass?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What is the difference between mass number relative atomic mass and average atomic mass?
What is the difference between average atomic mass and mass 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 average of the mass numbers of an elements isotopes?
the Atomic Mass
Why is the atomic mass of an element an average?
The atomic mass is an average because most elements consist of a mixture of isotopes.
Elements are ordered according to what?
average atomic mass number
How would the modern periodic table would be different if elements were arranged by average atomic mass instead of by atomic number?

An average of the masses of all the naturallly occurring isotopes of an 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.
What is the difference between mass number relative atomic mass and average atomic mass?
Do the elements in a row on the periodic table have the same average atomic mass?
no.
What is the difference between average atomic mass and mass number?
What elements has an average atomic mass nearest to 31?
It's is element
