Zinātne paliek atmiņā, ja definīcija ir saistīta ar kaut ko izmērāmu vai novērojamu.
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+.
Konkrēts pārbaudes punkts
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.
