In the model shown, what is represented by the purple spot?

• proton

• neutron

• electron

• shell

In the model shown What is represented by the green spot?

• proton

• neutron

• electron

• nucleon

Answer explanation

A nucleon is the name given to particles in the nucleus and can be either a proton or a neutron especially here in the diagram where it it not clear which is which.

In the model shown, what is represented by the purple line?

• proton

• neutron

• electron
