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!!!
