1. Definition of Isotopes: Isotopes are variants of a particular chemical element that have the same number of protons (atomic number) but different numbers of neutrons. This results in different mass numbers for the isotopes of the same element. 2. Fundamental Particle of Difference: The fun...
The beta decay is the decay of electron or positron from a radioactive nucleus. The atomic number of an atom is the number of protons present in the nucleus and the mass number is the total number of protons and neutrons present in the nucleus....
How do radioactive isotopes differ from isotopes? Atoms: All of the elements that we know to exist are listed on the periodic table. If you notice, the atomic masses of each element are different, and they are generally decimal values. This value is the weighted average of each isotope for...
Different isotopes of the same element (same element with different amounts of neutrons) do not have the same atomic mass. Carbon-13 has an atomic mass of 13 amu. Atomic weight, unlike the weight of an object, has nothing to do with the pull of gravity. It is a unitless value that ...
If you are given the abundance of each isotope of an element, how do you find the average atomic mass?Isotopes and natural Abundance:Isotopes are atoms that belong to the same chemical element but have different masses. These differences in their masses c...
