We use no with a noun. No = not a or not any:
example:
- They had to walk because there was no train. (= there wasn't a train)
- There were no banks open. (= there weren't any banks)
NONEWe use none alone (without a noun):
- How much money have you got? 'none.'
- none of these banks
- none of m money
- none of it/us/you/them
example:
- None of the girls I met were English.
