Which phenomenon explains why electrons exist outside calculated orbitals?

💡 Explanation

Quantum tunneling allows electrons to 'tunnel' through energy barriers, therefore they have a non-zero probability of existing outside their predicted orbital radius, because the wavefunction has a decaying exponential tail, rather than the energy overcoming all barriers.
