It is an oxidizing agent that, by virtue of its accepting electrons, is itself reduced in the process. A gradient of electrochemical potential, usually for an ion that can move across a membrane. An electron donor is a chemical entity that donates electrons to another compound. An electron shell is the outside part of an atom around the atomic nucleus. It is a group of atomic orbitals with the same value of the principal quantum number n. Any of various molecules that are capable of accepting one or two electrons from one molecule and donating them to another in the process of electron transport. The collective term for all possible frequencies of electromagnetic radiation. The amount of work needed to move a unit charge from a reference point to a specific point against an electric field. A subatomic particle with a negative elementary electric charge.
