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.

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 relative abundance of each isotope of an element determines its?
The relative abundance of each isotope of an element is used to determine its atomic mass. This is the weighted average of all naturally occurring isotopes.
Which two notations represent atoms that are isotopes of the same element?
The two notations represent atoms that are isotopes of the same element is 121 Sn and 119 Sn. The atomic mass of an element is defined as the weighted average mass of that elements naturally occurring isotopes.
Is an average mass of the different isotopes of the element?
Yes, weighted by how often the isotopes are found in nature.
What is the number of neutrons in the element silver?
Silver has 2 different naturally occurring isotopes:Silver-107 (51.35%) - 60 neutrons - mass 106.9389 amuSilver-109 (48.65%) - 62 neutrons - mass 108.9393 amuThe masses in amu differ from the mass number of the isotope because of the "mass defect, which in silver is slightly negative as is typical of elements in the middle of the binding energy curve. Also the mass of Silver on the periodic table of 107.912 amu is a weighted average the two isotopes masses. This is the number the chemist wants as he rarely cares about isotopes. If you want to count neutrons, you need a table of the isotopes of the elements, not just a periodic table. This is available in nuclear engineering, health physics, etc. texts.
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.
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.
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 a weighted average of the masses of all of the naturally occurring isotopes of an element?
The mean Atomic Mass.
When the masses of all naturally occurring isotopes of a particular element are averaged the result is called an elements what?
The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
When the masses of all the naturally occurring isotopes of a particular element are averaged the result is called the elements what?
The weighted average of all of the natural occuring isotopes for a particular element is called its Atomic Weight (or Relative Atomic Mass)
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 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.
Which statement best explains why most atomic masses on the periodric table are decimal numbers?
Atomic masses are a weighted average of the naturally occurring isotopes.
What element has the neutron number of 30.69?
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.
Why atomic weight of chlorine is 35.5 though isotopes of chlorine 35 and 37?
The atomic weight for each element on the periodic table represents a weighted average of the masses of all naturally occurring isotopes of an element. Because of this, the elements do not have whole-number atomic weights. An exception is the atomic weight for some elements written inside parentheses. These elements do not have stable isotopes and the atomic weight listed is the atomic weight for the longest lived isotope.
