ELI5: If electrons and protons are oppositely charged, why aren't they attracted to each other in the nucleus of the atom?
gpt
Electron degeneracy pressure and the pauli exclusion principle. The force of this is greater than the electromgnetic force. 
Two fermions cant occupy the same quantum state, unless gravity overcomes this as in a nuetron star.

eseentially the force attracting protons and electrons is weaker than one that is keeping them apart. Think of it like an airplane- how can it fly if gravity is attracting it. Well the force of lift is overcoming the force of gravity. No different with electrons and protons.
