If an atom is unstable it can become stable by the gain or loss of electrons.
Bauxite ore is one of the primary source of aluminum but it must first be chemically processed to produce alumina (aluminum oxide). The next step of aluminum production is smelting of alumina using an electrolysis process (Hall-Heroult process). This electrolysis process is driven by electrical current. Electrolyte (molten salt) with immersed carbon anodes is used in order to dissolve the alumina. Carbon anodes are carrying electrical current and thee chemical bond between aluminum and oxygen in the alumina is broken.
Animal cells (which are Eukaryotes) contain a nuclues, while Bacterial cells (which are Prokaryotes) do not contain a nucleus.
En las arqueas, generalmente se encuentra en la forma L-isomérica, mientras que las bacterias y eucariotas tienen la forma D-isomérica. Una segunda diferencia es la presencia de un enlace éter en oposición a los lípidos enlazados a éster que se encuentran en eubacterias y eucariotas.
