Properties of yttrium
Here is a list of some physical properties and chemical properties of yttrium.
Physical properties of yttrium
- Yttrium is solid metal having a silvery white metallic appearance.
- Out of all the isotopes of yttrium, the stable isotope is 89Y.
- Yttrium has an atomic mass 88.906 u and its density is 4.472 g/cm3.
- The melting point and boiling point of the yttrium metal is 1799 K and 3203 K respectively.
Chemical properties of yttrium
- Yttrium forms a thin oxide layer in the air and this layer prevents it from further oxidation.
