Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
The chart to the right gives the isotope
name, element name, number of protons, and Isotope Protons Neutrons
number of neutrons of three isotopes. Hydrogen-1 1 0

1. What do you notice about the isotope
number and the sum of protons and Uranium-235 92 143
neutrons?




2. The element symbol for uranium-238 is . This means U-238 has a total mass of 238
and contains 92 protons. Write the element symbols for the isotopes in the table:

Hydrogen-1 Carbon-12 Uranium-235



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?


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

A. Does a reaction occur?
