Question

A. Beta radiation is more penetrating than alpha radiation.
B. Beta radiation is less ionising than alpha radiation.
C. Beta radiation consists of helium nuclei.
D. Beta radiation is emitted from the nucleus.

Answer

The correct answer is A: Beta radiation is more penetrating than alpha radiation..

Explanation

The correct answer is A: Beta radiation is more penetrating than alpha radiation.. This supports the learning objective "Represent beta decay using a nuclear equation." in Nuclear equations 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 Nuclear equations idea: Beta radiation is less ionising than alpha radiation.; Beta radiation consists of helium nuclei.; Beta radiation is emitted from the nucleus..

Common mistake

Misunderstanding Beta Decay Representation

Students often confuse the representation of beta decay with that of alpha decay, incorrectly including mass changes.

Remember that beta decay does not change the mass number; only the atomic number increases by one. Focus on the correct nuclear equation format.
