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 the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
What else can I help you with?
What ios the average atomic weight?
The average atomic weight of an element is the average of all the known isotopes of that element along with their popularity. It would be calculated by gathering all the known isotopes of one element and individually multiplying them by percentage of occurrence.
What is the weighed-average mass of all the known isotopes for an element called?
The weighted-average mass of all the known isotopes for an element is called the atomic weight or atomic mass. It is calculated by taking into account the abundance of each isotope and its mass to determine the average mass of all isotopes present in nature for that element.
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.

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.
The various atomic weights of the same element are called?
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
Does isotopes only occur on heavier element?
No - the lightest element Hydrogen has three known isotopes
Atoms of the same element that differ in the number of neutrons they contain are known as?
they are known as isotopes. Dont ask people to do your homework
What is the difference between the atomic number and the atomic weight of the known elements as listed on the periodic table?
The atomic number of the element is the number of protons or number of electrons in an atom of the element . The atomic weight of the element is the ratio of the mass of the atom to the 1/12th of the mass of the atom of carbon 12.
If an element had three isotopes with known masses what other information is needed to find the average atomic mass of the element?
The abundance percentage of each isotope
What is the name for atoms of an element that have different masses?
An atom or element that have different masses are known as isotopes.
