Document Summary
Che002a test chapter 8 periodic table. 12 multiple choice questions: -calculate ionization energy rh(1/n^2)z^2. The answer rydberg equation: desire for atom to gain electron. Related to both ionization energy(>0) and electron affinty(<0) -en is prop to (i-ea) Electronegativity: make good acidic oxides like so2. The answer nonmetals: metals are good at this because they are easily ionized-low ionization energy. The answer reducing agents: -when tabulated values for ie are given, just add up ie from table. More accurate because these values are experimentally determined. The answer adding tabulated values: -half-filled, no electron electron repulsion through pairing -filled shells, mimic noble gas type configuration. The answer stable shells: when atoms gains electron which are usually nonmetals, energy required is this -energy to add electron is negative and increases negatively up and right on pt. The answer electron affinity: nonmetals are good at this, more likely to gain electrons and accept them by taking away.
