Planetary Bohr Model ng Technetium (Tc)
Description
Silvery-gray metal. First synthetically produced element.
Uses
Added to iron in quantities as low as 55 part-per-million transforms the iron into a corrosion-resistant alloy.
Sources
Made first by bombarding molybdenum with deuterons (heavy hydrogen) in a cyclotron.
Pronounciation (English)
