Chemistry 5.3

Like charges

• repel

• attract

Which charges would push each other away?

• Negative, positive

• Negative, neutral

• positive, positive

• positive, neutral

The strong nuclear force acts between

• electrons and protons

• only protons and protons

• only protons and neutrons

• all nucleons

Nucleons are

• in the nucleus

• orbit the nucleus

• protons and electrons

• another type of neutrons

Which particle is not considered a nucleon?

• Proton

• Neutron

• Electron

The strong nuclear force is strong

• always

• only at short distances

• only at long distances

Which force can occur over a longer distance?

• strong nuclear force

• repulsive electric force

Which force is stronger in this case?

• Strong nuclear force

• Repulsive electric force

Which force is stronger in this case?

• Strong nuclear force

• Repulsive electric force

Why is the repulsive electric force (REF) stronger than the strong nuclear force (SNF) in this picture?

• Because the protons are far apart

• Because the SNF works at long distances

• Because the REF is weak at short distances

• Because the SNF overpowers the REF in this case
