A physicist is designing a scale model of a chlorine atom for a science museum. In the real atom, the radius of the chlorine nucleus is approximately 4.0 × 10-15 m, while the covalent radius of the chlorine atom is approximately 1.0 × 10-10 m.
In the exhibition hall, the model of the chlorine atom is a large sphere with a radius of 25 m. Which of the following objects would best represent the radius of the chlorine nucleus on this same scale?
A dust particle of radius 0.1 mm0.1\text{ mm}0.1 mm
A mustard seed of radius 1.0 mm1.0\text{ mm}1.0 mm
A glass marble of radius 1.0 cm1.0\text{ cm}1.0 cm
A tennis ball of radius 3.3 cm3.3\text{ cm}3.3 cm
