Draw a diagram to illustrate your explanation of how the charge of a single electron was determined.
I'm suppose to draw a picture to show how they determined electrons were negative, but am unsure of what to draw for it.
One of my ideas is to draw a cathode ray tube with both ends labeled as cathode(negative) and anode(positive).
But I am not sure if there are any better ideas swell.
I think it might be a good idea to read up on the Millikan oil drop experiment.
For example:

My drawing should include a negative and positive charged plate with atoms being suspended inside with some flowing towards the negative plate and others flowing to the charge plate.
Would this be suffice?
I prefer that to your cathode ray tube, but you better add explanation of why some are falling and some are rising :)
Thanks for the help!
You are welcome. Good luck.
Your idea of drawing a cathode ray tube is a great way to illustrate the determination of the negative charge of an electron. Here's how you can draw the diagram:
1. Start by drawing a straight tube with a clear path from one end to the other. Label one end as the cathode (negative) and the other end as the anode (positive).
2. Inside the tube, draw a stream of particles traveling from the cathode to the anode. These particles are the cathode rays, which were observed during early experiments.
3. To represent the particles, draw small, arrow-like shapes to show their direction of movement. Make sure to draw multiple arrows to indicate that there are many particles.
4. You can also add a labeled electrical power supply connected to the cathode and the anode to show the source of the electric potential difference.
5. Finally, you can add a labeled observation screen at the end of the cathode ray tube. This screen was used to detect the behavior of the cathode rays.
By drawing this diagram, you'll be able to explain that when a high voltage is applied between the cathode and the anode, cathode rays are formed and move from the negative cathode to the positive anode. The behavior of these rays, such as their deflection by electric and magnetic fields, led to the discovery of the negatively charged particle we now know as the electron.
