The 3s orbital of sodium is only half-filled, so the electron in the 3s orbital of metallic sodium also belongs to the conduction band in the metal. This allows sodium to conduct electricity well.

Question

Quizplus · Accepted Answer

In metallic sodium, the 3s orbital is half-filled, and the electron can move freely, contributing to the conduction band, which allows sodium to conduct electricity efficiently.

The 3s Orbital of Sodium Is Only Half-Filled, So the Electron
