Q:

Where does silicon come from?

A:

Quick Answer

The element silicon is created through a process where carbon and sand are heated to temperatures close to 3,992 degrees Fahrenheit. Silicon is also very abundant in the Earth's crust and is the seventh most plentiful element in the universe. Silicon was first discovered by a Swedish chemist named Jons Jacob Berzelius in 1894.

  • Q:

    What is anomeric carbon?

    A:

    Anomeric carbon is carbon on which anomers rotate. The carbonyl carbon found in the open chain becomes anomeric carbon in the crystallized structure, which is also the most iodized carbon found in the ring. Depending on the orientation of the group that is attached to the anomeric carbon, ketose carbohydrates and cyclized aldose can adopt either a or b anomeric configuration, states Emory University.

  • Q:

    Who discovered silicon?

    A:

    Silicon was first isolated in the laboratory of Swedish chemist Jöns Jacob Berzelius in 1824. Berzelius extracted his sample by heating potassium in an earthenware vessel until the silicate rock began to break down. When he rinsed away the impurities, Berzelius was left with a sample of almost pure silicon.
