GIANT COVALENT STRUCTURES - chemguide

3/10/2018· Note: The logic of this is that a piece of graphite ought only to conduct electricity in 2-dimensions because electrons can only move around in the sheets - and not from one sheet to its neighbours. In practice, a real piece of graphite isn''t a perfect crystal, but a host of small crystals stuck together at all sorts of angles.

Silicon - Wikipedia

Silicon and silicon carbide readily react with all four stable halogens, forming the colourless, reactive, and volatile silicon tetrahalides. Silicon tetrafluoride also may be made by fluorinating the other silicon halides, and is produced by the attack of hydrofluoric acid on glass. [71]

structures and physical properties of period 3 elements

13/8/2020· Silicon is a non-metal, and has a giant covalent structure exactly the same as carbon in diamond - hence the high melting point. You have to break strong covalent bonds in order to melt it. There are no obviously free electrons in the structure, and although it conducts electricity, it doesn''t do so in the same way as metals.

Ionic and Metallic Bonding

Solids do not conduct electricity (electrons are tightly bound to ions) In aqueous solution, or when melted to a liquid, ionic compounds do conduct electricity (ions are now free to move). This is often an identifying feature of an ionic solid. Tend to be soluble in 2 O
