( Any suitable example of molecular substances)

*One example of non molecular substances and give reason for your choice ( Any suitable example of non molecular substances and state specifically characteristics.)

[E.g – Iron, because it has high melting point]

- must relate specificly to the the characteristics of molecular substances
