The main blocks of the traditional periodic table (i.e., the s, f, d, and p blocks) are in fact presented in the order l = 0, 3, 2, 1, highlighting that this arrangement is indeed illogical. Of note, elements H and He are placed in two different positions to reflect their dual nature in terms of atomic structure and chemical properties.

Molybdenum - Wikipedia

The black disulfide is the main mineral. It is roasted in air to give the trioxide: 2 MoS 2 + 7 O 2 → 2 MoO 3 + 4 SO 2. The trioxide, which is volatile at high temperatures, is the precursor to virtually all other Mo compounds as well as alloys. Molybdenum has several oxidation states, the most stable being +4 and +6 (bolded in the table at ...
