In this episode you will learn: - The atomic number is the number of protons and uniquely identifies an element. - Mass number is the sum of protons and neutrons; the difference between mass number and atomic number equals the neutron count. - Isotopes are atoms of the same element with different numbers of neutrons, while ions are atoms that have gained or lost electrons. - Atomic radius generally decreases from left to right across a period and increases from top to bottom down a group. - Ionization energy follows the opposite trend of atomic radius, increasing across a period and decreasing down a group.
