I know the innermost ring can hold 2, then 8, then 8...but I forgot the 4th and 5th. I've got a semester test next week and this is the only question I need help on. Thanks. :)
How many electrons can the 4th and 5th energy shells hold?
I'm not 100% sure about how this works with the Bohr model, but each energy level in an atom or molecule can only hold 2 electrons. Check the link to the tutorial, it might help a little.
