What are the names or if not have a name the formula of the following KCH3COO
Mg(CN)2
BaCrO4
Pb3+(SO4)3
KOH

idk tbh

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.
