4. c. Beta particle
A beta particle is a negatively charged particle. To figure out which particle is negatively charged, you can recall some basic knowledge about particle physics. In this case, the beta particle is known to be negatively charged. This information can be verified through various sources such as textbooks, scientific articles, or educational websites that explain the properties and characteristics of different particles.
5. a. Alpha particle
An alpha particle is the same as a helium nucleus. To determine which particle is equivalent to a helium nucleus, you need to understand the composition of an alpha particle. An alpha particle consists of two protons and two neutrons, which is the same composition as a helium nucleus. This information can be found in physics or chemistry textbooks, or by researching online resources that explain the structure and properties of particles.
6. b. Gamma particle
A gamma particle is pure energy. To identify which particle is pure energy, you must understand that gamma particles are electromagnetic radiation. They have no mass or charge, and they purely exist as a form of energy. This knowledge can be acquired through studying physics concepts related to electromagnetic radiation or through research from trusted sources.
7. a. Alpha particle
An alpha particle increases the atom number by 1. To determine which particle increases the atom number by 1, you should know that an alpha particle consists of two protons and two neutrons. When an atom loses an alpha particle, its atom number decreases by 2. Conversely, when an atom gains an alpha particle, its atom number increases by 2. By comparing this information to the available options, you can conclude that an alpha particle increases the atom number by 1.
8. b. Gamma particle
A gamma particle has no effect on the atomic number. To determine which particle has no effect on the atomic number, you have to know that gamma particles are electromagnetic radiation. Since they do not consist of any particles or carry a charge, they have no impact on the atomic number. This information can be obtained from resources that discuss the properties and interactions of electromagnetic radiation.
9. c. Beta particle
A beta particle decreases the atomic number by 2. To determine which particle decreases the atomic number by 2, you need to understand the concept of beta decay. During beta decay, a neutron is converted into a proton and a beta particle is emitted. As a result, the atomic number increases by 1 (proton) and the atomic mass remains the same (as the proton and beta particle mass are negligible compared to the neutron). By comparing this information, you can conclude that a beta particle decreases the atomic number by 2.
