Particles Lesson 2 Starter

What is the strong nuclear force

• The force responsible for chemical bonds between atoms

• The force that binds protons and electrons together in the atom

• The force that keeps electrons in orbit around the nucleus

• The force that binds protons and neutrons together in the nucleus

What is the range of the strong nuclear force

• Up to 2 fm

• Up to 3.5 fm

• Up to 5 fm

• Up to 10 fm

When is the strong nuclear force attractive

• Below 0.5fm

• Between 0.5 and 3.5fm

• Between 3.5fm and 5fm

• Above 5fm

When is the strong nuclear force repulsive

• Below 0.5fm

• Between 0.5 and 3.5fm

• Between 3.5fm and 5fm

• Above 5fm

What is the range of the electrostatic force

• Up to 5fm

• Up to 1cm

• Up to 1m

• Infinite range

Why don't we bother with gravity when looking at nuclear stability

• Too strong

• Super weak

• Doesn't act between nucleon

• Doesn't act between nucleons and electrons

Up to how many protons would stable atoms have same proton number as neutron number

Reorder the following in order of strength

• Strong

• Electromagnetic

• Weak

• Gravitational
