a. Beta particle
a. Beta particle (Decreases the atomic number by 1)
b. Gamma particle (Is pure energy)
c. Alpha particle (Increases the atomic number by 2)
To match the given statements with the correct answer, we need to understand the properties of the particles mentioned.
1. Is a negatively charged particle: This statement refers to a particle carrying a negative charge. The answer is (a) Beta particle.
2. Is the same as a helium nucleus: This statement refers to a particle that is identical to a helium nucleus, which consists of two protons and two neutrons. The answer is (c) Alpha particle.
3. Is pure energy: This statement refers to a particle that does not have any rest mass and exists as energy. The answer is (b) Gamma particle.
4. Increases the atom number by 1: This statement refers to a particle that adds one proton to an atom, thereby increasing its atomic number. The answer is (a) Beta particle.
5. Has no effect on the atomic number: This statement refers to a particle that neither adds nor removes protons from an atom, thus not affecting its atomic number. The answer is (b) Gamma particle.
6. Decreases the atomic number by 2: This statement refers to a particle that removes two protons from an atom, resulting in a decrease in its atomic number. The answer is (c) Alpha particle.
Matching the statements with their respective answers:
a. Beta particle: - Is a negatively charged particle, Increases the atom number by 1.
b. Gamma particle: - Is pure energy, Has no effect on the atomic number.
c. Alpha particle: - Is the same as a helium nucleus, Decreases the atomic number by 2.
