Giant Covalent Flashcards
What is giant covalent bonding?
A type of covalent bonding where atoms are bonded in a continuous network.
Name two examples of giant covalent structures.
Diamond and graphite.
Describe the structure of diamond.
Each carbon atom is bonded to four other carbon atoms in a tetrahedral structure.
Describe the structure of graphite.
Layers of carbon atoms bonded in hexagonal patterns with weak forces between layers.
What are the properties of diamond?
Extremely hard, high melting point, non-conductive, but good at transferring heat!
What are the properties of graphite?
Conducts electricity, slippery (used as lubricant in machinery) , high melting point.
What is another example of a giant covalent structure besides carbon allotropes?
Silicon dioxide (SiO2)
Are bonds in giant covalent structures strong or weak?
Very strong due to extensive covalent bonding.
