C2 : Graphite Flashcards
Properties of Graphite
. High melting and boiling point
. Soft and slippery
. Excellent conductor of heat and electricity
What element is Graphite formed from
Carbon
How much covalent bonds do each carbon atom in Graphite form
3
What shape do the carbon atoms form
Hexagonal rings
Why does Graphite have a high melting / boiling point
Because there are lots of covalent bonds that make up the hexagonal rings
Why is Graphite soft and slippery
The hexagonal rings are arranged in layers and are held by weak intermolecular forces that allow them to slide over each other
Why does Graphite contain delocalized electrons
Carbon atoms in Graphite have only 3 covalent bonds meaning a single electron is left free, this electron is a delocalized electron
Why can delocalized electrons carry charge
They can move
What are some characteristics of Graphite
. Based on carbon so it’s not a metal
. Similar to metals in terms of properties
. Both graphite and metals have delocalized electrons
