Question 5

A scale model of an atom is being planned for a science centre.

The diameter of this atom is 20 000 times the diameter of its nucleus. In the model, the nucleus will be represented by a bead 3.0 mm across.

A designer says that the model atom should be 6.0 m across.

Evaluate the designer's statement.
