An isotope is a variant of the atom with the same number of protons but more or fewer neutrons.
The Atomic Mass is an average of the isotopes of the element. The average is weighted according to the relative abundance of such isotopes.

What is the average atomic mass of an element is the average atomic masses of what kind of isotopes?
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
What is necessary to calculate the atomic mass of an element is?
You need to know the atomic # or the masses of each isotope of the element.
Which are the two important particles in an isotope?
The atomic particles of an isotope are the proton, electron and neutron
How many protons and neutron and electron and nucleus electron cloud are the in curium?
Curium has 96 protons. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; for the isotopic masses of curium read at the link below.
What is the atomic mass of an element and how is it determined?
The atomic mass of a radioactively stable element is defined as the mass, usually measured in grams, of Avogadro's Number of atoms of the element as obtained from natural sources on Earth. For most elements, this atomic mass will be an average, weighted by natural isotope percentages, of the individual isotopes of the atom that naturally occur, but some elements have only one naturally occurring non radioactive isotope. The scale of atomic masses is now established by defining the mass of a carbon-12 isotope to be exactly 12. The atomic masses of other elements are defined by their mass ratios to a carbon-12 isotope.

Why do atomic masses have decimal points and look scary?
Most elements exist in the form of isotopes: these are atoms all have the same number of electrons and protons but the number of neutrons varies from one isotope to another. As a result, each isotope of an element has a different atomic mass. The atomic mass given for an element is an average of these atomic masses, weighted together according to the isotope's abundance on earth. That is why they have decimal points and fractional parts.They d not look at all scary! After all, what can numbers do to you? You are much bigger than them!
What is an element that has the same chemical properties but different atomic masses?
an isotope
What is necessary to calculate the atomic mass of an element is?
You need to know the atomic # or the masses of each isotope of the element.
Which are the two important particles in an isotope?
The atomic particles of an isotope are the proton, electron and neutron
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.
How many protons and neutron and electron and nucleus electron cloud are the in curium?
Curium has 96 protons. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; for the isotopic masses of curium read at the link below.
Do uranium isotopes have different atomic masses?
Yes, each isotope has a specific atomic mass; this is correct for all the elements.

State the name and the mass of the isotope relative to which all atomic masses are measured?
Carbon-12 is used as the standard by which the atomic masses of other nuclides are measured.
What atoms has different masses but the same atomic number?
they're called isotopes.
Why are most atomic masses a decimal?
The atomic mass of an isotope of an element is the mass of the nucleons (neutrons + protons) in an atom of that isotope. This is nearly, though not exactly, equal to the number of nucleons, and so is nearly a whole number.The main cause for the atomic mass being fractional is that most elements have numerous isotopes, each with a different number of neutrons and so a different atomic mass. The atomic mass for an element is the average of the atomic masses of all its isotopes, weighted together in the proportion of the isotopes' abundance on earth. It is this weighting together that results in the numbers being fractional.
