When looking at the different types of electromagnetic radiation, we typically write them in the order of gamma radiation, and then x -rays, and then ultraviolet, and then visible.
00:26
From visible, it's infrared, and then infrared to microwave, and then microwave to radio wave.
00:42
And in this direction we show an increase in energy and frequency, but a decrease in wavelength.
01:02
So to select the arrangement of the electromagnetic radiation, starting with the lowest energy and increases to the greatest energy, we're going to start with radio and end with gamma.
01:16
So it's going to be radio.
01:23
It looks like the last one.
01:25
Radio infrared ultraviolet gamma.
01:30
So i'll refer to that as d, the last answer.
01:34
Radio infrared ultraviolet gamma.

For the energy level diagram of oxygen, we'll start with electrons in the 1s orbital.
01:51
And then we'll go to the 2s.
01:56
And then after the 2s, we go to 2p, and there are three of those orbitals at 2p.
02:15
And before filling in those, let's determine how many total electrons we have for oxygen...
