Periodic Trends in the Oxidation States of Elements. 1. Variation Of Oxidation State Along a Period. While moving left to right across a period, the number of valence electrons of elements increases and varies between 1 to 8. But the valency of elements, when combined with H or O first, increases from 1 to 4 and then it reduces to zero.

Thus semiconductors with band gaps in the infrared (e.g., Si, 1.1 eV and GaAs, 1.4 eV) appear black because they absorb all colors of visible light. Wide band gap semiconductors such as TiO 2 (3.0 eV) are white because they absorb only in the UV. Fe 2 O 3 has a band gap of 2.2 eV and thus absorbs light with λ < 560 nm.
