Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
What is needed to find the average atomic mass of the element?
the mass of the 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.
Which best describes the definition for the atomic mass of the element?
it is the weighted average of the masses of an element's isotopes.
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.
What is the average mass of the isotope of an element?
the average mass numbers of the isotopes of an element
Why are the atomic mass numbers of an element not hole numbers?
Its the average of the weight of the different isotopes of that element.
Which is the average of the mass numbers of an element's isotopes?
the Atomic Mass
Why is there an average atomic mass?
There is an average atomic mass because all atoms of the same element do not have the same amount of neutrons (isotopes), therefore variations in atomic mass exist. The average atomic mass of an element is the estimated average of all the atoms of the same element, given the average of different isotopes in a scientific sample.
What is the definition for atomic mass?
so the mass of an atom is determined by the number of protons and neutrons in an element. For a given element, the number of protons is the same but the number of neutrons can vary (an element can have various isotopes). Therefore, the average atomic mass of an element is simply a weighted average of the masses of all the isotopes of that element. (a weighted average means that how common an isotope is is taken into account when incorporating it into the average, so rare isotopes will not count as much as common isotopes)
How is the atomic mass of an element is affected by the distribution of its isotopes in nature?
Isotopes have a different amount of Neutrons. The atomic mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
What is weighted average mass of an element isotopes?
average atomis mass
What Have different isotopes of the same element?
Isotopes of the same element have different numbers of neutrons and mass.
What does isotopes have to do with mass numbers?
isotopes of the same element have different mass number
What is the average of the mass numbers of isotopes of an element?
the atomic mass
What is the average mass of the mixture of an elements isotopes?
All of the isotopes in an element's atomic masses divided by the amount of isotopes there are is the weighted-average mass of the mixture of an elements isotopes.
How is the atomic mass of an element affected by the distribution of its isotopes in nature?
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
