The Metallic WorldStreaming Video - 2014
Metals allow the transfer of electrons through a process called oxidation-reduction, or "redox," when one species gains electrons while another loses them. Chemists use electron transfers to power the batteries in our flashlights, phones, or cars. In biochemistry trace metals, such as cobalt in Vitamin B12, often drive essential chemical reactions for human health. Redox reactions also occur without metals, as in lightening hair color.
