### Nuclear Decay Processes

The diagrams provided illustrate three types of nuclear decay processes: gamma decay from excited cobalt-60, alpha decay from polonium-210, and beta minus decay from potassium-40. Each diagram is structured to demonstrate the transformation of nuclear particles during these decay processes.

#### 13. Excited Cobalt-60, Gamma Decay
- **Diagram Explanation**:
  - The diagram is a linear sequence of boxes.
  - The first box represents the original state of cobalt-60 in its excited form.
  - An arrow in the second box indicates the process of gamma decay, where energy is released while the element remains the same.
  - The third box signifies a resulting neutral particle, depicted as a plus sign, highlighting that there is no change in the element's atomic mass or number.

#### 14. Polonium-210, Alpha Decay
- **Diagram Explanation**:
  - Similarly structured linear diagram.
  - The first box represents the initial state of polonium-210.
  - The arrow in the second box denotes the emission of an alpha particle.
  - The third box, marked with a plus sign, signifies the formation of a new element with a reduced atomic number, reflecting the release of an alpha particle (2 protons and 2 neutrons).

#### 15. Potassium-40, Beta Minus Decay
- **Diagram Explanation**:
  - The linear sequence diagram begins with the original potassium-40 state.
  - The arrow represents the beta minus decay process.
  - The third box contains a plus sign to indicate a transformation, where a neutron is converted into a proton, emitting an electron (beta particle) and an antineutrino. This results in an element with an increased atomic number but the same atomic mass.

These diagrams provide a graphical representation of the decay processes, aiding in the visualization and understanding of nuclear transformations.
