Which of the following statements about alpha particles is true? A) They have greater penetrating power than beta particles B) They are high-energy electrons C) They can be stopped by a thick metal barrier D) They consist of two protons and two neutrons
Understand the Problem
The question is asking for the identification of the true statement regarding alpha particles from the given options. This involves knowledge of nuclear physics and the properties of alpha particles.
Answer
They consist of two protons and two neutrons.
The final answer is that alpha particles consist of two protons and two neutrons.
Answer for screen readers
The final answer is that alpha particles consist of two protons and two neutrons.
More Information
Alpha particles are essentially the nucleus of a helium-4 atom, providing them with a consistent composition of two protons and two neutrons, making them relatively large and positively charged compared to other types of radiation like beta particles.
Tips
A common mistake is thinking that alpha particles have high penetrating power or are highly energetic electrons. It's crucial to remember they have low penetrating power, being stopped by materials as light as paper.
