Define the term, provide the units, and show how the trend behaves through the periodic table. a. Atomic Radius: distance from the nucleus to the outermost electron. DECREASES INC. b. First Ionization Energy: the energy required to remove the outermost electron. INCREASES DEC c. Electronegativity: the ability of an atom to attract electrons in a chemical bond. INCREASES DEC d. Ionic Radius: the distance from the nucleus to the outermost electron of an ion. Cations get smaller, anions get bigger e. Electron Affinity: the amount of energy released when an atom gains an electron. Same as EN, but Cl has the greatest electron affinity 2. For each of the following sets of atoms, rank from smallest to largest according to the atomic radius. a. Li, C, F F, C, Li b. Li, Na, K Li, Na, K c. Ge, P, O O, P, Ge d. C, N, Al N, C, Al 3. For each of the following sets of atoms, rank from lowest to highest first ionization energy...
