c.Alpha particle

4. c.Alpha particle

5. a.Beta particle
6. b.Gamma particle

Let's compare the items in column A with the items in column B.

1. Column A: Helium atom
Column B: Alpha particle

- A Helium atom is made up of two protons, two neutrons, and two electrons. It carries a net charge of zero.
- An Alpha particle is a helium nucleus, which means it contains two protons and two neutrons. It has a net charge of +2.

Therefore, a Helium atom is different from an Alpha particle.

2. Column A: Electron
Column B: Beta particle

- An Electron is a subatomic particle carrying a negative charge of -1 and is commonly found orbiting an atom's nucleus.
- A Beta particle refers to either an electron or a positron that is emitted during the process of beta decay. It carries a charge of -1 or +1, respectively.

Therefore, an Electron is the same as a Beta particle.

3. Column A: Pure energy
Column B: Gamma particle

- Pure energy refers to the conversion of matter into energy or the state when matter is completely transformed into energy.
- A Gamma particle refers to a photon emitted during gamma decay. It is a high-energy electromagnetic radiation.

Therefore, Pure energy is different from a Gamma particle.

In summary:
- A Helium atom is different from an Alpha particle.
- An Electron is the same as a Beta particle.
- Pure energy is different from a Gamma particle.

To determine the matches between columns A and B, we can examine the properties of each item in column A and compare them to the properties of the particles in column B.

1. Colume A: 4. Is the same as a Helium atom.
Column B: c. Alpha particle.

Explanation: A Helium atom consists of two protons and two neutrons in its nucleus, which is the same composition as an alpha particle. Therefore, the match is between 4 and c.

2. Column A: 5. Is an electron.
Column B: a. Beta particle.

Explanation: An electron is a fundamental particle with a negative charge. A beta particle, on the other hand, can be either an electron or a positron (a positively charged electron). Since electrons fall under the category of beta particles, the match is between 5 and a.

3. Column A: 6. Is pure energy.
Column B: b. Gamma particle.

Explanation: Pure energy refers to electromagnetic radiation, and gamma particles are high-energy photons, or electromagnetic radiation. Therefore, the match is between 6 and b.

So, the matches between column A and column B are:
4 - c
5 - a
6 - b
