Atoms and nuclear radiation

Question

A. A high-speed electron emitted from the nucleus
B. A helium nucleus emitted from the nucleus
C. Electromagnetic radiation emitted from the nucleus
D. Neutrons emitted from unstable nuclei

Answer

The correct answer is A: A high-speed electron emitted from the nucleus.

Explanation

The correct answer is A: A high-speed electron emitted from the nucleus. This supports the learning objective "Define radioactive decay as the process in which an unstable nucleus emits radiation." in Radioactive decay and nuclear radiation because it uses the correct atomic and nuclear radiation relationship for Atoms and nuclear radiation. The other options are less suitable because they do not match the required Radioactive decay and nuclear radiation idea: A helium nucleus emitted from the nucleus; Electromagnetic radiation emitted from the nucleus; Neutrons emitted from unstable nuclei.

Common mistake

Misunderstanding Radioactive Decay

Students often confuse radioactive decay with a predictable process, thinking they can determine when an unstable nucleus will decay.

Emphasize that radioactive decay is a random process, and it is impossible to predict the exact moment an individual unstable nucleus will decay.
