Do covalent compounds conduct electricity?
Yes
No
Why can't covalent substances conduct electricity?
They have delocalised electrons
The ions are trapped in the bond
The electrons are trapped in the bond
They can conduct electricity
Why can metals conduct electricity?
They have positive and negative ions
The have delocalsied ions
They can't conduct electricity
They have delocalised electrons.
Why do covalent molecular substances have low melting and boiling points?
The covalent bonds need to be broken
The weak inter-molecular forces need to be broken
Why do ionic substances conduct when they are molten or in solution?
