1.Each element is a substance composed of atoms with an identical number of protons in their nuclei. For example, an atom of the element nitrogen always has seven protons.
2.All elements except hydrogen also have neutrons in their nuclei, and the element's atomic weight is the sum of the weights of the protons and neutrons.
3. "Isotope" refers to variant forms of elements with different neutron counts -- each variant, with its unique neutron count, is an isotope of the element.
4.The periodic table of the elements lists the atomic weight of each element, which is the weighted average of the isotope weights based on the abundance of each.
5. You could easily look up the percent abundance of each isotope in a chemistry book or on the Web, but you may have to calculate the percent abundance by hand, for example, to answer a question on a chemistry test at school. You can perform this calculation for only two unknown isotope abundances at a time.
