Super! Good visualisation! As you move

**away**from the centre of the merry-go-round, there is**more empty**space. Which means that you can have more horses there.Back to electrons! We said that electrons go around the nucleus in orbits. The number of orbits depends on how many electrons are there in the atom. The orbits are labelled by numbers. As you can see, the number can be \(n = 1,\, 2, \, 3, \, \ldots\).

A given orbit with number \(n\) can hold a maximum of \(2 n^2\) electrons. So, for example, the \(n = 3\) orbit can hold \(2 \times 3^2 = 18\) electrons.

A given orbit with number \(n\) can hold a maximum of \(2 n^2\) electrons. So, for example, the \(n = 3\) orbit can hold \(2 \times 3^2 = 18\) electrons.

How many electrons can the \(n=4\) orbit hold?

- \(16\)
- \(8\)
- \(24\)
- \(32\)
