Lewis Structures Step by Step

Molecular Formula: Show Steps Predict 3D Geometry For charged species, you can use formats like SO4-2 or NH4+.
Alternatively, use a caret (^) for superscript-style charges: e.g., PO4^3- or NO^+.
To specify a central atom if desired, add (c) after it, e.g., N(c)NS for N₂S with a central nitrogen.
