Teadus jääb meelde, kui definitsioon seotakse millegi mõõdetava või vaadeldavaga.
The quantum numbers label allowed electron states; they are not little planetary coordinates around the nucleus.

Sodium has 11 electrons; its outer 3s electron helps explain why sodium readily forms Na+.
Konkreetne kontrollpunkt
Start with the nucleus, then move outward. Protons identify the element; electrons occupy quantum states rather than miniature planetary tracks. Electron configuration is the bridge from atomic structure to chemistry.
