Explain why a solution that is 1.3 M HF and 1.3 mM KF is not a good buffer. HF is a strong acid and cannot be used in a buffer system. The ratio of acid to conjugate base is outside the buffer range of 10:1. KF is not soluble in water and cannot be used in a buffer system. The two species are not a conjugate acid base pair.

if two electrons have the same n, the same ℓ, and the same ml, then they are in the same orbital. the pauli exclusion principle states that no two identical fermions (a fancy word for electrons and other subatomic particles like electrons) may occupy the same quantum state in an atom simultaneously.
