True or false
graphite is made up of carbon atoms arranged in layers
true
Graphite is made up of atoms
carbon
why does graphite conduct electricity
because it has delocalized electrons that are free to move within the layers
each carbon atom in graphite bonds to four other carbon atoms
False
Each carbon atom forms covalent bonds
three
What are alltropes
alltropes are different forms of the same element in the same physical state . Example: graphite or diamond
Graphite can conduct electricity due to the presence of free electrons
Ture
sodium chloride conducts electricity when or dissolved in water
molten/dissolved
Why graphite is soft and slippery
The layers are held together by weak van der waals forces, so they can slide over each other easily.
Sodium chloride is a covalent compound
False
is an allotrope of carbon that is very hard.
Diamond
Why does graphite have a high melting point?
Because strong covalent bonds exist between carbon atoms.
the layers in graphite can slide over each other easily
true
Graphite has a structure made of hexagonal layers
layered
What is the structure of graphite?
Graphite consists of carbon atoms arranged in a hexagonal rings.Each carbon atom is bonded to three others , forming flat sheets
