For Periodic Structures, I need to know,
1. how it's arranged
2. groups, periods, ect.
3. reactivity

And for atomic structures:
1. Info on Electrons, Nuetrons, Protons
2. energy levels
3. nucleus.

I basically need information on all of these things.
If you can't answer both, just answer one.
Please, this is urgent.
