  4. appearance • Metalic luster • Ductile • Silver • Reactive metal

  5. Properties • Symbol: Y • Atomic Number: 39 • Melting point: 1500 degree Celsius • Boiling point: 3336 degree Celsius • Electronic shell: [ Kr ] 4d1 5s2 • Relatively stable in airuntil it is divided. • Yttrium will melt or burn in air if the temperature exceeds . • Natural yttrium has only 89 yttrium.

  6. Where is it used ? what is it? • When refining metals yttrium is used to remove impurities. • Used in metal alloys • Reacts with water, which makes it decompose and release hydrogen gas.

  7. what is it? Rare earth metal and also a rare chemical

  8. Uses • Used in laser systems • Potential use in glass and ceramic formulas • Deoxider for vanadium and other metals • Catalyst in the polymerization of ethelyn.

  9. Where can it be found? • Color television • Fluorescent lamps • Energy saving lamps • glasses

  10. Health effects • Lung embolism: damp and gasses can be in haled with air that has yttrium when it is exposed in a very long time. • Cancer:causes lung cancer when yttrium is inhaled • Threat to liver: when yttrium accumulates with the body

  11. Effect on the environment? • Yttrium leaks in to the environment when the household items gets thrown away and also in petrol producing industries yttrium is dumped. • Which has negative effects on the water animals as their cell membranes will be killed and it will be hard for them to reproduce. Also it has a negative impact on the nerve system.
