Student Exploration: Nuclear Decay
Vocabulary: alpha particle, atomic number, beta particle, daughter product, gamma ray, isotope, mass number, nuclear decay, positron, radioactive, subatomic particle
Gizmo Warm-up
While most atoms are stable, some are radioactive, which
means that they have a tendency to undergo spontaneous nuclear decay. The decay of radioactive atoms generally results in the emission of particles and/or energy.
Several types of nuclear decay can be explored with the
Nuclear Decay Gizmo. On the Gizmo, check that Alpha
decay and Uranium are selected.
1.Click Play (
), and then click Pause (
) when the alpha particle is clearly visible. What is
an alpha particle made of? Protons and neutrons
2.Click Play and observe. Besides the alpha particle, what else is emitted from the nucleus
during alpha decay? Gamma Rays
Gamma rays are energetic electromagnetic waves; they
are often emitted in nuclear decay.
Activity A: Alpha decayGet the Gizmo ready :
•Click Reset (
).
•Check that Alpha decay and Uranium are
selected.
Question: How does alpha decay change the nucleus of a radioactive atom?
1.Calculate : Turn on Write equation. What you see is an equation that shows the original uranium atom on the left. The boxes on the right represent the daughter product—the atom produced by radioactive decay—and the emitted alpha particle.
