wavelength

What is the distance between two equivalent points on a wave?

200

frequency

What is the number of waves that pass through a given point per second?

300

Electromagnetic radiation

What is energy that moves as a wave at the speed of light? (Includes visible light, UV, infrared, X-rays etc.)

400

atomic orbital (and what are the 4 types and how many electrons fit in each)

What is an area outside the nucleus where you are likely to find electrons? (s-2, p-6, d-10, f-14)

500

The difference between an energy level and an energy sublevel, in terms of the house analogy.

What is: energy levels are like the floors of a house, where higher floors correspond to higher energy levels, while energy sublevels are like the different types of rooms in a house, which have different numbers of beds?
