Match the particle to its description
Column A
1. This particle cannot penetrate very far into other materials
2. Can be absorbed by a sheet of paper
3. Can penetrate other materials moderately
4. Can be absorbed by lead
Column B
A. Beta particle
B. Gamma particle
C. Alpha particle
Column A:
1. This particle cannot penetrate very far into other materials - C. Alpha particle
2. Can be absorbed by a sheet of paper - A. Beta particle
3. Can penetrate other materials moderately - B. Gamma particle
4. Can be absorbed by lead - A. Beta particle
Matching the particles to their descriptions:
Column A:
1. This particle cannot penetrate very far into other materials - C. Alpha particle
2. Can be absorbed by a sheet of paper - A. Beta particle
3. Can penetrate other materials moderately - B. Gamma particle
4. Can be absorbed by lead - B. Gamma particle
To match the particles with their descriptions, we need to understand the properties of each particle. Let's break down each particle and their corresponding descriptions:
Column A:
1. This particle cannot penetrate very far into other materials - This description indicates a particle that has a limited ability to penetrate other materials.
2. Can be absorbed by a sheet of paper - This suggests a particle that can be stopped by a relatively thin barrier like paper.
3. Can penetrate other materials moderately - This implies a particle that has a moderate ability to penetrate other materials.
4. Can be absorbed by lead - This indicates a particle that can be blocked by a dense material like lead.
Column B:
A. Beta particle - Beta particles are high-energy electrons or positrons emitted during certain radioactive decays. They have a negative charge and can penetrate further into materials than alpha particles but can still be blocked by obstacles such as paper or aluminum.
B. Gamma particle - Gamma particles are a type of electromagnetic radiation. They are highly energetic and have no mass or charge. Gamma particles can penetrate most substances, including thick materials like lead.
C. Alpha particle - Alpha particles are composed of two protons and two neutrons, making them identical to a helium-4 nucleus. They have a positive charge and are relatively large and heavy. Alpha particles can be stopped by a sheet of paper or a few centimeters of air.
Now, let's match the particles to their descriptions:
1. This particle cannot penetrate very far into other materials - C. Alpha particle
2. Can be absorbed by a sheet of paper - A. Beta particle
3. Can penetrate other materials moderately - B. Gamma particle
4. Can be absorbed by lead - A. Beta particle
So, the matching particles to their descriptions are as follows:
1. C. Alpha particle
2. A. Beta particle
3. B. Gamma particle
4. A. Beta particle
