C2—Bonding Flashcards
What is Metallic bonding
How metal atoms bond to each other
They form a LATTICE of Ions surrounded by a sea of delocalised electrons
Why are metals conductive
As electrons are free to move
What is Ionic bonding
Metal bonding to a non metal
What should the charges in an ionic compound add up to
0
What are Ions arranged in
Arranged in Lattice of repeating units of positive and negative Ions.
Positive ions are called
Cations
Negative ions are called
Anions
What are ionic compounds also called
Salts
Why can ionic structures conduct electricity
Ions are free to move in this states and they carry charge
What are covenant bonds
How non metals bond to each other
What do covenant bonds do
Share electrons to get a full outer shell
What do simple covenant bonds have
Low boiling points
Weak intermolecular forces
What is diamond
One do the hardest known substances due to its very strong bonds
Giant Covalent Bond
Carbon made
What is Graphine
Delocalised electrons form weak bonds between layers
Can conduct electricity as these electrons can move
Layers can slide past each other
What is a Giant Covalent bond
Giant molecules with very high melting points
