Atom or ion O, oxygen, 8 electrons

Element Charge

Configuration 1s² 2s² 2p⁴

Noble gas core Write the core in brackets, like [Ar], and draw only the orbitals after it.

Order

4s comes before 3d, in the order they fill.

Exceptions

Cr, Cu, Ag, Au, Pd and a few others are drawn as they really are (Cr is [Ar] 4s¹ 3d⁵).
