Observe some of the phenomena around your home. Look for something that you can’t explain right away, but that you could test wi
th an experiment. Then, design an experiment that you could conduct at home. Make sure to identify the independent, dependent, and controlled variables. You should also write your own hypothesis. You don’t need to perform the experiment, just identify the variables and write a hypothesis.
This is dependent on how many shells/layers/energy levels the element has. The first shell can only hold 2 electrons however every shell beyond that can hold 8 electrons
