A few Chemistry Questions (True or False) I really need your help please look!!!?

[Mathew B]

Please try to answer as many as you can if you are unsure please put that you are unsure rather than confusing me. Thanks so much to all of you who took your time out to answer!!!

All true or false:

1) Aristotle believed matter was made of atoms.

2) Of the three subatomic particles, the electron is the smallest.

3) Frequency is the number of waves that pass a given point, usually in one second.

4) Light has both properties of particles and waves.

5) An atom is in an excited state when it has its lowest energy.

6) The Bohr model of the atom shows electrons in areas called energy levels.

7) Electrons in pairs have opposite spin.

8) The p orbitals look like dumbbells.

9) When electrons move to lower levels they lose energy.

10) Visible light is a form of electromagnetic radiation.

11) There could be eight electrons in the first energy level

DONEEE!!!! THANKS SO MUCH FOR YOUR HELP!!!
