5. Decreases the atomic number by 2: c. Alpha particle
1. An alpha particle is the same as a helium nucleus.
To determine this, we need to know that an alpha particle consists of two protons and two neutrons, which is the same composition as a helium nucleus. Therefore, the answer is c. Alpha particle.
2. A gamma particle is pure energy.
To determine this, we need to know that gamma particles are high-energy photons (particles of electromagnetic radiation). They do not have any mass or charge, and they exclusively exist as energy. Therefore, the answer is b. Gamma particle.
3. Beta particle increases the atom number by 1.
To determine this, we need to know that a beta particle is an electron emitted during beta decay. During beta decay, a neutron is converted into a proton, and an electron (beta particle) is emitted. Since a proton has a positive charge and an atom's atom number is determined by its number of protons, emitting a beta particle increases the atom number by 1. Therefore, the answer is a. Beta particle.
4. Gamma particle has no effect on the atomic number.
To determine this, we need to know that gamma particles are high-energy photons (particles of electromagnetic radiation). They do not have any mass or charge and thus do not result in any changes to the atomic composition or atomic number of an atom upon their emission. Therefore, the answer is b. Gamma particle.
5. Alpha particle decreases the atomic number by 2.
To determine this, we need to know that an alpha particle consists of two protons and two neutrons. When an alpha particle is emitted from an atom, it reduces the number of protons (and neutrons) in the parent atom by two. As the atomic number is determined by the number of protons, an alpha particle emission decreases the atomic number by 2. Therefore, the answer is c. Alpha particle.
