Molybdenum By maddy
The Basics
- Boiling point: 4,639 celcius or 4912 K
- Melting point: 2,623 celcius or 2896 K
- group: transition metal
But... What does this have to do with molybdenum?
You're about to find out.
Appearance
- hard, shiny
- metal
- looks like lead
History
Orginin of the Name
Greek word for lead: molybdos
molybdenum pronounced: mo-LIB-de-num
Discovery
- Scientists thought it was lead
- 1778, Carl Whelhem Scheele- not lead
- makes acid (molybic acid)
- hard to find metal
- 1781, Peter Jacb Hjlem- found metal
How?
Molybic acid+ carbon+ linseed oli= paste
paste+ heat=molybdenum
Uses
Industrial
Steel
- steel+molybdenum=really strong
- 300,000 lbs per square inch
- high temperatures
Other
- molybdenum disulphide
- electrical cords
- aircraft parts
Medicinal
- tetrathiomolybdate can treat wilson's disease
- naturally forms compound with copper
- sucks copper out
Biological
Enzyme: protein that helps chemical reactions happen
In humans
- sulfite oxidase: sulfite➡️sulfate
- breaks down animo acid
- Alehyde oxidase: breaks down:
- things we shouldn't eat
- medicines
In plants
- nitrogenase: helps plants like beans grow
- plants turn nitrogen into to digestible form
- we need for us to grow
Nothing could be alive without molybdenum
