Answer 2

quantum numbers are the sets of numerical values that give acceptable values to the Schrödinger wave equation for hydrogen atom.
the number of types of quantum numbers has no universal answer, but in practical there are four types of quantum numbers..
1. principal, 2. magnetic 3. angular. 4. spin
