Oxidizing Agents, Bohr vs. Rydberg and the Zeeman Effect

1. Why is the peroxide anion such a strong oxidizing agent? 2. Describe qualitatively how the conclusions of Bohr and Rydberg are essentially the same? 3. Which property of the hydrogen atom does the Zeeman Effect illustrate? Explain this.

Octet rule

Elements in the first short period are limited by the octect rule whereas those in the higher period can expand their valence shells. Describe what this means, account for this phenomenon and give an example of each.

Wavelentgth, Quantum numbers questions

If energy is absorbed by a hydrogen atom in its general state, the atom is excited to a higher energy state. For example, the excitation of an electron from the level with n=1 to the level n=3 requires radiation with a wavelength of 102.6 nm. Which of the following transitions would require radiation of longer wavelength then
