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)
Which are the two important particles in an isotope?
The atomic particles of an isotope are the proton, electron and neutron
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.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
true
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 an element that has the same chemical properties but different atomic masses?
an isotope
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 an electron emitted from an atom into two nuclei with smaller masses is?
its called an isotope c:
Which are the two important particles in an isotope?
The atomic particles of an isotope are the proton, electron and neutron
What atoms has different masses but the same atomic number?
they're called isotopes.
What are the units for average relative atomic masses?
The unit is such that the isotope Carbon 12 is exactly 12 by definition.
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.
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 does na12 look like?
If you mean an isotope of 23 Na; They all "look" the same; they simply have different masses.
Is this statement true or false The isotope hydrogen-1 is the standard used for the relative scale of atomic masses?
true
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 average mass of an isotope?
You must specify the element whose isotopes you want the weighted average mass for. Otherwise there is no answer as just averaging the masses of isotopes without accounting for how much of each isotope is present in a sample of an element is meaningless. Also averaging masses of isotopes of different elements is also meaningless.
