(Select all that apply).
high melting and boiling point
strong
doesn't conduct electricity
conducts electricity
weak
low melting and boiling point
|
Do giant covalent structures have high or low melting points?
high
low
|
Diamond and graphite are both made from the element , and are examples of covalent structures. Their atoms are arranged in a regular repeating structure with many multiple covalent bonds between each atom.
|
Which of these is an example of a giant covalent structure?
ammonia
diamond
water
carbon dioxide
|
Graphite is able to conduct . This is because each carbon atom has one electron, which can move freely, and so is able to carry charge.
|
Which structure is shown in the image?
diamond
carbon
graphite
glass
|
Which of the following statements are true of diamond?
each carbon atom is bonded to 4 other carbon atoms
it is made up of silicon and oxygen
each carbon atom is bonded to 3 other carbon atoms
it conducts electricity
|
Two substances made from the same element, that are in the same physical state, but that have different structures, are called .
|
What is the formula of Buckminsterfullerene?
C20
C60
C40
C80
|
F are allotropes of carbon, made by bending sheets of graphene into hollow structures. Nanotubes made from these are useful in electronics. This is because each carbon atom has one delocalised which can carry charge.
|
Giant covalent structures have high melting points because there are strong bonds between which require a lot of energy to break.
