the boiling point of silicon, in degrees Celsius, is between 2500 and 3645. However, the melting point, is around 1,140,40 degrees Celsius, as you may have noticed, its very high, and this is because its extremely high in oxygen.
The melting point of the element, silicon, is about: Melting Point: 1687 K (1414°C or 2577°F) Boiling Point: 3538 K (3265°C or 5909°F) Resource: http://education.jlab.org/itselemental/ele014.html You can find the freezing point of the element there as well. Thank you. :}
The attraction forces or the attraction between the bonds is relatively high as opposed to H2O or water which the bonds aren't as strong giving it a relatively low boiling point (: I feel like that helped :D
