What else can I help you with?
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.
How many electrons does the heaviest naturally occurring element have?
Uranium, number 92 is the last of the naturally occurring elements and, of course, it has 92 electrons.
What is the naturally occurring actinide that is used in nuclear reactors?
We look to the naturally occurring element uranium as a nuclear fuel.
The lanthanide that is not naturally occurring?
This chemical element is promethium (Pm).
What is the average atomic mass compared to atomic mass?
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
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.
How do you calculate the average mass of a naturally occurring element?
By multiplying the mass number of each naturally occurring isotope of the element by the fractional abundance of the same isotope, then adding all the resulting products.
Are the mass number is an average of the masses of all naturally occurring isotopes of an element?
Yes they do.
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.
Is thalium man made?
Thallium is a naturally occurring element in the Earth's crust. It is not a man-made element.
Why are the masses given in the periodic table described as being average masses?
The given mass of an element on the periodic table is determined by calculating the weighted average of all naturally occurring isotopes of that element. If the element does not occur in nature, the atomic mass of the most stable isotope is given.
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.
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.
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 a weighted average of the masses of all of the naturally occurring isotopes of an element?
The mean Atomic Mass.
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?
