Planetary Bohr Model ng Praseodymium (Pr)
Lewis Dot Diagram ng Praseodymium (Pr)
Description
Silvery white, moderately soft, malleable, ductile metal.
Uses
Used with neodymium to make lenses for glass maker's goggles since it filters out the yellow light present in glass blowing. Alloyed with magnesium creates a high-strength metal used in aircraft engines. Makes up 5% of Mich metal.
Sources
Obtained from same salts as neodymium.
Pronounciation (English)
pra-si-eh-DIM-i-em
