Is the mass number an average of the masses of all naturally occurring isotopes of an element?
No, it isn't. It is the atomic weight that is a weighted average of the mass of each of the naturally occurring isotopes of an element. The mass number, or A, is the number of protons and neutrons (the so-called nucleons) in the nucleus of an atom of an element. The atomic number, or Z, is the number of protons in the nucleus of an element.

Is gallium a naturally occurring isotopes?
Yes, gallium does have naturally occurring isotopes. The most common stable isotopes of gallium are gallium-69 and gallium-71, with gallium-69 being more abundant at about 60% and gallium-71 about 40%.
Explain how it is possible for Bromine to have a mass of 79.9 amu on the periodic table but NOT have a naturally occurring isotope with a mass of 80 amu?
The mass listed on the periodic table for an element is a weighted average of the masses of its naturally occurring isotopes, taking into account their relative abundance. In the case of bromine, its mass is 79.9 amu because it includes the isotopes with masses slightly below and slightly above 80 amu. It is possible for an element’s average mass to not match any individual isotope due to the varying abundances of its isotopes.
Is aluminium natural or syntheti?
Aluminium is an element, it is not synthetic.
Which element is the heaviest actininde that occurs naturally on earth?
Uranium is the heaviest naturally occurring actinide.
What is naturally occurring solid inorganic compound or element?
Diamonds are naturally occurring solid inorganic compounds composed of carbon atoms arranged in a crystal lattice structure.
What is the average of all the naturally occurring isotopes of a particular element?
The average of all the naturally occurring isotopes of a particular element are an element's atomic Mass.
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.
What is the weighted-average mass of all the known isotopes for an element?

Are the mass number is an average of the masses of all naturally occurring isotopes of an element?
Yes they do.
When the masses of naturally occurring isotopes of a particular element are averaged the result is called the elements of what?
When the masses of naturally occurring isotopes of an element are averaged, the result is called the element's average atomic mass.
What is a weighted average of the masses of all of the naturally occurring isotopes of an element?
The mean Atomic Mass.
What is the weighted average of the atomic masses of an element's naturally occurring isotopes is called the?
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.
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).
Is radon the element naturally occurring?
The radon isotopes 222Rn and 220Rn are natural isotopes.
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 tin an isotope?
Tin is an element with ten naturally occurring isotopes.
