Nuclear Chemistry : Isotopes Quiz

*Theme/Title: Isotopes
* Description/Instructions
An isotope is an atom with varying numbers of neutrons. This does not affect the atomic number of the atom, but it does affect the mass. Protons and neutrons have an assumed mass of 1, so the combined number of protons and neutrons in the nucleus equals the atom's mass number. To determine the number of neutrons in an atom, subtract the atomic number from the mass number. The proper way to notate an isotope is to use the element's name or symbol with a dash and the element's mass number. Ex: U-238, or Uranium-238. For the following quiz, you will need a periodic table. Select the best answer to the question. Good luck.
