Flashcards in Covalent Bonding Deck (15):
What are covalent bonds?
A shared pair of electrons between two non metals
What are intRAmolecualr bonds?
Bonds inside the molecule
-These are VERY STRONG COVALENT BONDS
what are IntERmolecular bonds
Forces between molecues, strength depends on the side of the molecule.
The increase in the size of molecules=STRONGR molecular forces
Why does graphite leave a mark on paper when rubbed?
-The weak forces allow there to be a thin layer of graphite left on the paper
What allows graphite to conduct electricity
They have de localised electrons
Why is graphite a good lubcricant?
High Melting Point
Why are diamonds so strong
They have many extremely strong covalent bonds
How many bonds hold the carbon atoms together in graphite?
What holds together the layers of graphite?
Weak intermolecular forces
What element is graphite and diamond made of ?
What structures do diamond and graphite form?
How many bonds hold the carbon atoms in diamonds?
Is graphite a good electrical conducter
Is graphite hard or soft
