C2 Flashcards
What is the structure of fullerenes
Good catalyst
Arranged in hexagons
Used to silver drugs to the body
Why do + and - ions attract to each other
To make a full putter shell
Why is ionic bonding good
To gain a stable electronic configuration
When is ionic bonding used
When an atom either wants to lose or gain an electron to have a full putter shell
When is covalent bonding used
When atoms share electrons to have a full putter shell
How are ionic compounds formed
+ and - ions attract to each other and bond together
What forces keep ionic compounds together
Electrostatic attraction
What is the structure of diamond
Hard
Doesn’t conduct electricity
Lots of energy needed to break bonds
High melting point
What is the structure of graphite
Takes lots of energy to break the bonds
High melting point
Soft and slippery
Conducts electricity
What is the structure of graphene
One layer of graphite
Delocalised electron
Strong and light
What do negatives and positives do
Bond to for ionic bonding
