Those answers troubled him since he was not sure what a negative answer—the opposite of some property—could mean.
The uncertainty principle, a fundamental law of physics (the science of matter and energy), says that the pathway traveled by very small particles like an electron can never be defined perfectly. For a long time, people thought that this number was a fixed property of the element in question. Electrons are actually much smaller than protons and neutrons. Quantum number mℓrepresents the magnetic properties of the electron. The electrons closest to the nucleus are held to the atom with a stronger force than the electrons farther from the nucleus; some atoms hold on to their outer electrons with a vengeance, while others are a bit more lax.
