match these with this
Column B
a.Alpha particle
b.Gamma particle
c.Beta particle
a. Alpha particle
b. Gamma particle
c. Beta particle
Column B would match with the following:
a. Alpha particle (5. Is the same as a helium nucleus)
b. Gamma particle (6. Is pure energy)
c. Beta particle (4. is a negatively charged particle)
4. b. Beta particle - A beta particle is a negatively charged particle. To determine this, you can refer to the process of beta decay, which is the emission of a beta particle (usually an electron or positron) from a nucleus.
5. a. Alpha particle - An alpha particle is the same as a helium nucleus. To verify this, you can look at the composition of an alpha particle, which consists of two protons and two neutrons, identical to a helium nucleus.
6. b. Gamma particle - A gamma particle is pure energy. Gamma radiation is a type of electromagnetic radiation characterized by high energy and penetrating power.
7. a. Alpha particle - An alpha particle increases the atom number by 1. This is because when an alpha particle is emitted during radioactive decay, the atom loses two protons and two neutrons. This results in a decrease in the atom number by two.
8. b. Gamma particle - A gamma particle has no effect on the atomic number. Gamma radiation is a form of high-energy electromagnetic radiation without any charge or mass, so its emission does not cause any change in the atomic number.
9. c. Beta particle - A beta particle decreases the atomic number by 2. During beta decay, a beta particle (either an electron or positron) is emitted from the nucleus, causing an increase in the atomic number by one unit due to the conversion of a neutron into a proton. Since two beta particles are emitted, the net decrease in the atomic number is two.
