Hydrogen (H) — electron configuration — PeriodicTable

Hydrogen (H) — electron configurationHydrogen has 1 electrons, arranged 1s1. Written on the previous noble gas that is 1s1, and the shells hold 1 electrons from the innermost outwards.Hund's rule leaves 1 unpaired electron in the ground state, which is what makes the free atom paramagnetic. The subshells of Hydrogen in filling order; each orbital holds at most two electrons, of opposite spin.

The periodic table, read every way a chemistry course asks for. This tool needs JavaScript; these are the pages it offers:

Periodic table — every property, plotted and coloured

Periodic table coloured by any property

Plot a property against atomic number

Plot one element property against another

Electron filling and configuration of every element

Isotopes and isotopic pattern of every element

Element data sheet — every property of every element

About — where the element data comes from
