D OXIDATION-REDUCTION REACTION

Acid, when referring to the science term are proton donors that yield hydronium ions in a water solution, or electron-pair acceptors that combine with electron-pair donors or bases.
The element calcium, or Ca, is located in group 2, period 4 of the Periodic Table. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2. This can also be written as [Ar] 4s2, because the beginning of that electron configuration is the same as argon's. The 42 you mentioned in your question is referring to a specific isotope of calcium and has nothing to with the electron configuration.
Hydrogen only has one electron so it will form only one bond
Well, it can't make any in the dark, now can it? So if any metabolic processes are occurring, it will be used up.

Ferredoxins are iron-sulfur proteins that mediate electron transfer in a range of metabolic reactions.
NADH and FADH are Coenzymes which act as carriers of electrons, protons, and energy in metabolism.
Neon atoms have 8 valence electrons. Refer to the related link for an illustration of the electron dot diagram for neon.
