All the average molar masses of isotopes can be found on a Periodic Table.
What else can I help you with?
How are isotopes different than naturally occurring elements?
Isotopes are atoms of the same element with different numbers of neutrons, while naturally occurring elements refer to all atoms of a particular element found in nature. Isotopes have the same number of protons but different atomic masses, whereas naturally occurring elements have consistent atomic masses based on the average of all isotopes present.
Average weight of an element expressed in atomic mass units?
The average weight of an element is expressed in atomic mass units (amu) and is calculated based on the relative atomic masses of the isotopes of that element weighted by their abundance in nature. This value can be found on the periodic table for each element. For example, the average atomic mass of carbon is 12.011 amu.
What does the number 15.999 signify in the periodic table of elements?
As far as i know, its the atomic mass of oxygen
Do all isotopes only occur in heavier elements?
No, isotopes of light elements exist as well. For example, there are several isotopes of the lightest element, hydrogen.No, even the lightest element (hydrogen (H)) has isotopes. These are called Deuterium and Tritium.All elements have isotopes but some of them are very unstable and have disappeared in nature over time.
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.
Is an average mass of the different isotopes of the element?
The average atomic mass of an element is the weighted average of the masses of its isotopes, based on their abundance in nature. It is calculated by multiplying the mass of each isotope by its relative abundance, then summing these values together. This average mass is given on the periodic table.
What form is commonly found in nature?
The most stable of any element is found free in nature. Sometimes isotopes are also found along with the most stable of an element. Isotopes usually have short half life.
Where is rutherfordium found in nature?
Rutherfordium is a synthetic element and is not found in nature. It is produced in laboratory settings by bombarding heavy isotopes of other elements with high-energy particles.
How can one determine the atomic weight of an element?
The atomic weight of an element can be determined by calculating the weighted average of the masses of its isotopes, taking into account their abundance in nature. This information is typically found on the periodic table of elements.
The atomic weight of an element is determined by what?
The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass of the element.
How are isotopes different than naturally occurring elements?
Isotopes are atoms of the same element with different numbers of neutrons, while naturally occurring elements refer to all atoms of a particular element found in nature. Isotopes have the same number of protons but different atomic masses, whereas naturally occurring elements have consistent atomic masses based on the average of all isotopes present.

Is uranium an acid or a base?
Uranium is a metallic element and is not classified as an acid or a base. It is a radioactive element that can be found in nature as uranium-238 and uranium-235 isotopes.
What is the name of the number with a decimal found in an element box?
The number with a decimal found in an element box is called the "atomic mass." It represents the average mass of an element's isotopes, weighted by their natural abundance. This value is typically not a whole number due to the presence of isotopes and their varying proportions.
What does the number 15.999 signify in the periodic table of elements?
As far as i know, its the atomic mass of oxygen

Atomic mass used in a sentence?
The atomic mass of an element is the weighted average of the masses of all the stable isotopes of the element (if it has any), weighted by the natural occurrence levels of the isotopes in the elements as found on earth or in the atmosphere.
