How to Type Chemical Formulas

Typing chemical notation on a standard keyboard is difficult because elements like Carbon require subscripts (C₆), and ions require superscripts (Ca²⁺). Our tool makes this seamless.

1 Type the element symbol (e.g., "H") with your keyboard.
2 Click the subscript number (₂) from our chemistry keyboard.
3 Add arrows (→) or charge signs (⁺) as needed.
