Why is the atomic mass of an atom the average atomic mass?
It allows for the relative abundances of different isotopes.
How do the decimal places on the atomic masses of elements realate to isotopes?
The atomic mass of an element is the weighted average of masses of the isotopes of the element, weighted in proportion to their abundance.
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.
Atomic mass is equivalent to the number of?
The atomic mass is the mass of an atom of that element in AMUs. (Atomic Mass Units)The atomic number, however, is equivalent to the number of protons in an atom of that element.The mass number of an atom is the total number of protons and neutrons in the nucleus of an atom. This is therefore always a whole number. The relative atomic mass of an element is the weighted average of the masses of the isotopes relative to 1/12 of the mass of a carbon-12 atom.It is a weighted average as it takes into account the relative abundances of the different isotopes (atoms of the same element but with different numbers of neutrons) of an element. This number is found in the periodic table.For example chlorine has two isotopes, 35Cl and 37Cl, in the approximate ratio of 3 atoms of 35Cl to 1 atom of 37Cl.The number of protons and neutrons in a 35Cl atom must add up to 35, the mass number. The relative atomic mass of chlorine takes into account both isotopes and is therefore 35.5.
The average atomic mass of an element is the average of the atomic masses of its?
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
What is the same in isotopes?
isotopes always have the same? mass # & atomic #, or atomic # and atomic weight, or atomic # but different mass #'s
Do isotopes have the same atomic number and the same atomic mass?
No: They have the same atomic number but not the same atomic mass.
Does an isotope of an element have a different atomic mass?
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
What do two different neutral isotopes of the same element have in common nuclear number atomic mass nuclear mass atomic number?
The atomic number is the same for all isotopes.
Atoms that have the same atomic numbers but different atomic weights are called what?
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.
Two atoms with the same atomic number but different atomic weight?
Atoms of the same element have different isotopes, differing only in number of neutrons (so differing in mass number, atomic mass).
What are atoms with same atomic mass but different atomic numbers called?
Isotopes. The isotope has the same number of protons and electrons as the regular atom, but has more (or sometimes less) neutrons, and therefore its atomic mass is more (or less, depending on whether the neutrons have increased or decreased).
Why some isotopes were written without its atomic number?
Different isotopes of an element have the same atomic number, they (only) differ in (atomic) mass NUMBER.
What are the atoms called then they have the same atomic number but different mass numbers?
They are called as isotopes in which mass number differ by emmision of radiation
How it is different a.m.u of carbon isotopes?
Isotopes have same atomic no. but different atomic mass due to presence of extra neutrons in the nucleus
How is average weight of atomic mass computed?
the average atomic mass is computed by summing all isotopic weights of the isotopes of that element and then dividing this by the the total number of isotopes of that element (note that isotopic mass is exactly the same as atomic weight, except for isotopes).
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.
