Chemistry
Electron Configuration
Quick fact
The electron configuration of noble gases, like neon (1s² 2s² 2p⁶), makes them almost completely unreactive—a stability that drives chemical reactivity for all other elements.
Why this is interesting
You know that atoms are made of protons, neutrons, and electrons, but have you ever wondered where all those electrons actually live? Their address inside the atom isn’t random—it follows a strict, predictable pattern that explains why gold is gold, why neon glows, and why table salt forms.
