When a molecule loses electrons to another molecule or atom,that molecule has been Oxidized. The electron acceptor molecule has then gained two electrons and is said to have been Reduced.
- Oxidation is loss of electrons during a reaction by a molecule,atom or ion.Oxidation occurs when oxidation state of a molecule,atom or ion is increased.
- Reduction is the opposite process of oxidation.Reduction occurs when there is gain of electrons or oxidation state of a molecule,atom or ion decreases.

0/4 pts Question 5 Electrons exist in orbitals within an atom. Bohr's model described a single electron system well. But the energy level for orbitals change when as you add a second and more electron. In a single electron system, there are (a)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (b) sub-level(s) in the atom. In a multi-electron system, (c)_orbital(s) at the n-2 level. These n-2 orbital(s) exist at (d)sub-level(s) in the atom. Bohr was never...
