Ionic compounds do not consist of molecules, but covalent compounds generally do.
Why is it incorrect to refer to a molecule of an ionic compound?
As part of your answer, draw two scenes, representing atoms as circles:
a. Draw at least 6 copies of NaCl showing how it is bonded.
b. Draw at least 6 copies of BrCl showing how it is bonded.
Then explain what is meant by a molecule and why it is correct to state that most
covalent compounds exist as molecules, but ionic compounds do not exist as
molecules.
Take a picture of your drawing and explanation and insert it in the answer box.
