Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element".

Phase at STP: solid

Melting point: 1799 K (1526 °C, 2779 °F)

Boiling point: 3203 K (2930 °C, 5306 °F)

Density (near r.t.): 4.472 g/cm3

when liquid (at m.p.): 4.24 g/cm3

Heat of fusion: 11.42 kJ/mol

Heat of vaporization: 363 kJ/mol
