yes it does b/c the isotopes have different number of neutrons so therefore isotopes cause a change in mass.

What is an atom called when the number of neutron changes?
an isotope of an element
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
How is an isotope different from its original atom?
When an atom is of the same atomic number, atomic mass, etc. to the one on the periodic table (Lets use Boron for example) Then B is the regular atom. But if you change the number of neutrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B
What isotope of carbon has been chosen as the reference isotope for atomic mass units?
The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom (when the atom is motionless). Relative isotopic mass is the relative mass of a given isotope scaled with carbon-12 as exactly 12.
What isotope serves as the current standard for the atomic mass scale?
with C14 atom
What is an atom called when the number of neutron changes?
an isotope of an element
The mass of an atom compared to the mass of a carbon-12 atom is called the?
Isotope.
Which atom has an average mass not equal to its common isotope?
ChlorineMolar Mass: 35.5Most Abundant Isotope Mass: 35
If the number of neutrons in an atom changes what is formed?
isotope
If a hydrogen atom has a mass of 3 is it an isotope?
yes
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
Is the sum of the numbers of protons and the number neutrons in an atom is the mass number?
It is the mass number for that particular form of the atom - that particular isotope. An element can exist as more than one isotope and the atom's mass number is the (weighted) average of the mass numbers of all its isotopes.

How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
How much does a technetium atom weigh?
The mass an atom of technetium isotope 98 is 16,27.10e-23 g.
How do you determine the mass of atom using mass spectrometer?
Actually in mass spectrometer the isotopes of an element are separated by applying magnetic field.Each isotope is then compared with carbon-12 to get the atomic mass of that isotope.
What isotope of carbon has been chosen as the reference isotope for atomic mass units?
The atomic mass may be considered to be the total mass of protons, neutrons and electrons in a single atom (when the atom is motionless). Relative isotopic mass is the relative mass of a given isotope scaled with carbon-12 as exactly 12.
