, Gizmo Warm-up
The Nuclear Reactions Gizmo simulates a particle accelerator.
Particle accelerators speed up atoms to very high velocities, then
crash the atoms together with enough energy to cause changes called
nuclear reactions. There are three particle beams available in this
Gizmo, protons, neutrons, and helium-3 nuclei.

1. Click Fire Proton to engage the first particle beam.

What happens? A positron flew out

2. Colliding particles don’t always react. Click Reset, and then click Fire neutron.

A. Does a reaction occur? no

B. Explain: the fire neutron flew through
