Non - metals form what?
Anions
Solid ionic compounds don’t conduct because…….
The ions can’t move
When can the ionic compounds conduct?
When it is melted or dissolved because the ions can move
What is a covalent bond?
A covalent bond is a shared pair of electrons
Simple covalent substances have a low melting point so they are liquids and gases. This is because you only have to break…..
The weak intermolecular bonds to melt them
Giant covalent substances have high melting points so they are solids. This is because to melt them, you have to…..
Break the strong covalent bonds.
