The equation 146C → 147N + 0-1e represents beta-minus decay. This is because the atomic number is increased by one (from 6 to 7) and a beta particle (0-1e) is emitted, which consists of an electron.
To determine the type of radioactive decay modeled by the equation 146C → 147N + 0−1e, we need to understand the different types of decay and their characteristics.
In alpha decay (α decay), an alpha particle (α) is emitted from the nucleus. An alpha particle consists of two protons and two neutrons, which is the same as a helium nucleus. The equation would typically look like X → Y + α.
In beta-minus decay (β- decay), a neutron in the nucleus is converted into a proton, and an electron (0-1e) is emitted from the nucleus. The equation would usually be written as X → Y + 0-1e.
In beta-plus decay (β+ decay), a proton in the nucleus is converted into a neutron, and a positron (0+1e) is emitted from the nucleus. The equation would usually be represented as X → Y + 0+1e.
In gamma decay (γ decay), the nucleus is in an excited state, and it releases energy in the form of a gamma ray (γ) to transition to a lower energy state. This type of decay does not result in a change in the atomic number or mass number of the nucleus.
Looking at the equation 146C → 147N + 0−1e, we see that a neutron is being converted into a proton, and an electron (0-1e) is emitted. This indicates beta-minus decay (β- decay). Therefore, the equation models beta-minus decay.
So, the correct answer is: beta-minus decay.
