Question 1:

Which type of radioactive decay involves the emission of an alpha particle?

Explanation: The correct answer is A) Alpha decay. Alpha decay occurs when a nucleus emits an alpha particle, which consists of two protons and two neutrons.

Question 2:

Which type of radioactive decay involves the emission of a high-energy electron or positron?

Explanation: The correct answer is B) Beta decay. Beta decay involves the emission of a high-energy electron (beta-minus decay) or a positron (beta-plus decay) from a nucleus.

Question 3:

Which type of radioactive decay involves the emission of electromagnetic radiation?

Explanation: The correct answer is C) Gamma decay. Gamma decay involves the emission of electromagnetic radiation in the form of gamma rays, which are high-energy photons.

Question 4:

Which type of radioactive decay does not involve the emission of particles?

Explanation: The correct answer is C) Gamma decay. Gamma decay involves the emission of electromagnetic radiation (gamma rays) without the emission of particles.

Question 5:

Which type of radioactive decay is not affected by external factors such as temperature or pressure?

Explanation: The correct answer is C) Gamma decay. Gamma decay is not affected by external factors such as temperature or pressure since it involves the emission of electromagnetic radiation.
