The equation given represents beta-minus decay.
To determine which type of radioactive decay the given equation models, we need to understand the different types of decay and their characteristics.
In this equation, 146C represents the parent isotope, 147N represents the daughter isotope, and 0-1e represents the emitted particle. The subscripts and superscripts represent the atomic number and mass number, respectively.
Alpha decay occurs when an atomic nucleus emits an alpha particle, which consists of two protons and two neutrons (equivalent to a helium nucleus). However, in the given equation, we don't see any alpha particles being emitted.
Gamma decay is a type of radioactive decay that involves the emission of gamma rays, which are high-energy photons. However, in the given equation, we don't see any gamma rays being emitted.
Beta-plus decay, also known as positron emission, occurs when a proton in the nucleus is converted into a neutron, resulting in the emission of a positron (a positively charged electron). However, in the given equation, we don't see any positrons being emitted.
Beta-minus decay, also known as electron capture, occurs when a neutron in the nucleus is converted into a proton, resulting in the emission of an electron and an antineutrino. In the given equation, we see 0-1e, which represents the emission of an electron (0-1e), indicating beta-minus decay.
Therefore, the correct answer is: beta-minus decay.
