A science centre is making a large-scale model of an atom. The radius of the atom in the model is 3.0 m.
Four settings are available for the radius of the nucleus.
| Setting | Radius of nucleus |
|---|---|
| P | 3.0 × 10-1 m |
| Q | 3.0 × 10-2 m |
| R | 3.0 × 10-5 m |
| S | 3.0 × 101 m |
Which setting gives the best representation of the relative sizes of the nucleus and the atom?
Setting P
Setting Q
Setting R
Setting S
