Describing the … WebGenerally, the electrons are either added to or lost from the valence shell of an atom; the inner-shell electrons are more tightly bound to the positively charged nucleus and so do not participate in this type of chemical interaction. Ionization generally involves a transfer of electrons between atoms or molecules.
WebMethyl-coenzyme M reductase, responsible for the biological production of methane by catalyzing the reaction between coenzymes B (CoBS-H) and M (H3C-SCoM), hosts in its core an F430 cofactor with the low-valent NiI ion.
