  1. Identifying Elements: •Matt Hoke •Scott Swearingen •Kristina Byrd

  2. How is an element identified, and what makes it unique? •Elements are identified by how many protons each atom has. The atomic number is equal to the number of protons. •Protons are positively charged.

  3. How does mass tie in? •Atomic mass is determined by the combined total of protons and neutrons, which have no charge, in an atom. •Electrons have so little mass, it means almost nothing.

  4. Isotopes: •An isotope is a variation of an element, by adding more neutrons to an element. •Isotopes have the same atomic number, but different atomic masses.

  5. Radio Isotopes: •Radio isotopes are unstable isotopes, that release energy as they decay. •They have been used to tag certain cells to track and tag for medical procedures.
