This type of decay is associated with heavy, unstable nuclides. Since no stable isotopes exist above atomic number 83, alpha decay stabilizes those isotopes having a Z value greater than 83 by lowering both the mass number and the atomic number. As an alpha particle is emitted, the number of neutrons and protons decreases, creating a more stable type of atom. Because most elements exist as mixtures of several stable isotopes, the atomic mass of an element is defined as the weighted average of the masses of the isotopes.

  Alexandria 7 years ago An isotope is the different forms of an element with equal numbers of protons, but varying in the number of neutrons. An element is classified by its atomic number which is equal to the number of protons it has so every atom with that number of protons is considered the same element. For example Copper has an atomic number of 29, so there will always be 29 protons in the nuclei of that atom, there can't be 5 protons in copper, there can't be , there must always be 29 protons in copper. But there could be a different number of neutrons in the nuclei. The differing number of neutrons in the nucleus is how the Atomic Mass is determined. Atomic mass is the average of all the different isotopes. Hope this helps. I unfortunately am in the same boat as you with a bad science teacher. Good luck. Source s : Physical Science.
