yes it does b/c the isotopes have different number of neutrons so therefore isotopes cause a change in mass.
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
Adding the number of protons and neutrons in the nucleus of an atom gives the mass number of the isotope.
The atom is an isotope of helium called helium-4. It contains 2 protons and 2 neutrons in its nucleus, giving it a total atomic mass of 4 atomic mass units.
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
An atom with a different number of neutrons is called an isotope of the original element. Isotopes have the same number of protons (and thus the same element) but different numbers of neutrons.
Isotope.
Hydrogen atom has an average mass not equal to its common isotope. The most common isotope of hydrogen, hydrogen-1, does not have a neutron in its nucleus, while the average mass of a hydrogen atom accounts for the other isotopes of hydrogen which do contain neutrons.
No, a hydrogen atom with a mass of 3 is not an isotope of hydrogen. Hydrogen isotopes include protium (mass 1), deuterium (mass 2), and tritium (mass 3).
isotope
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro 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.
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
Adding the number of protons and neutrons in the nucleus of an atom gives the mass number of the isotope.
The mass an atom of technetium isotope 98 is 16,27.10e-23 g.
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.
The atom is an isotope of helium called helium-4. It contains 2 protons and 2 neutrons in its nucleus, giving it a total atomic mass of 4 atomic mass units.
