Electron Configuration

The electron configuration of hydrogen is 1s¹. This means it has one electron in the first energy level, specifically in the s orbital.

Hybridization Information

Hydrogen typically forms bonds using its 1s orbital. In molecules like methane (CH₄), carbon undergoes sp³ hybridization while hydrogen uses its unhybridized 1s orbital.

Key Properties

Hydrogen is the lightest element. Under standard conditions, hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible gas. It's the most abundant chemical substance in the universe.
