Negative Energy: Understanding Hydrogen's Electron

The video explains why the energy of an electron in a ground state hydrogen atom is negative. It compares a free electron, which is at an infinite distance from the nucleus and has zero energy, to an electron in an orbit under nuclear influence, which has negative energy. The video calculates the energy for both scenarios, showing that the bound electron is more stable due to its lower energy. This stability is contrasted with the instability of a free electron, leading to the conclusion that electrons prefer to exist in stable orbits rather than as free electrons.
