What are the characteristics of good quantum numbers and how do they help in solving the Schrdinger equation for a quantum system?

Good quantum numbers are properties of a quantum system that are conserved during a physical process. They include values such as energy, angular momentum, and spin. These numbers help in solving the Schrdinger equation by providing a way to simplify the equation and reduce the number of variables that need to be considered. By using good quantum numbers, the Schrdinger equation can be broken down into smaller, more manageable parts, making it easier to solve and understand the behavior of the quantum system.
