how to find isotopes

Every atom has a certain number of protons, electrons and neutrons. Protons carry a positive charge, electrons carry a negative charge and neutrons do not carry a charge. Protons and neutrons make up the nucleus or central part of the atom. Electrons orbit around the nucleus. Most atoms have isotopes that occur naturally. An isotope is an atom with a different number of neutrons, but the same number of protons and electrons. Each element has a standard number of neutrons that can be found by looking at a periodic table. From the periodic table, you will get the atomic number on the top left corner of the box. This is the number of protons. The atomic weight of the element can be found on the bottom of the box on the periodic table.
Find the element on the periodic table. Record the atomic weight (on the bottom) and the atomic number (top left).
Subtract the atomic number (the number of protons) from the rounded atomic weight. This gives you the number of neutrons in the most common isotope.
Use the interactive periodic table at The Berkeley Laboratory Isotopes Project to find what other isotopes of that element exist.
