Two atoms have the electron configurations 1s2 2s2 sp6 and 1s2 2s2 2p6 3s1. The first ionization energy of one is 2080 kJ/mol and that of the other is 496 kJ/mol Match each ionization energy with one of the given electron configurations.

For each chemical reaction listed in the table below, decide whether the highlighted atom is being oxidized or reduced or neither oxidezed nor reduced. a. 4HF (g) + SiO2 (s) - > SiF4 (g) + 2H20 (g) Higlithed: Si b.
