2 Go to Log in and access the Gizmo titled: NUCLEAR DECAY. Follow the instructions and complete the assignment below. 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 will be explored in this Nuclear Decay Gizmo. On the Gizmo, check that Alpha decay and Uranium are selected. Look closely at the Key so you know what you are looking at. 1. Click Play ( ), and then click Pause ( ) when the alpha particle is clearly visible and starts to jiggle(you may have to press play and reset several times). What is an alpha particle made of? 2. Click Play and observe again. Besides the alpha particle, what else is emitted from the nucleus during alpha decay? These are energetic electromagnetic waves that carry energy; they are often emitted in nuclear decay. How does alpha decay change the nucleus of a radioactive atom? Activity A: Alpha decay DO THIS BEFORE PROCEEDING Get our your Periodic Table of Elements Click Reset ( ). Check that Alpha decay and Uranium are selected. Be sure to study the chart titled: Nuclear Decay Symbols. 1. Predict: As you observed in the warm-up activity, an alpha particle consists of two protons and two neutrons. How will the emission of an alpha particle affect the following? A. The atomic number of the atom will: B. The mass number of the atom will : 2. Calculate: Click 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. A. In the top left box, type in the mass number of the daughter product. What number did you type in? B. In the bottom left box, type in the atomic number of the daughter product and now press Enter. What number did you type in? C.
