Inserting Chemical Equations in Notes
Chemical equation boxes (chem boxes) make it easy to type chemical formulas
and equations, such as .
As you type in a chem box, most of the formatting work is handled
automatically:
• Correct capitalization of most element symbols, such as Ag and Cl, is
automatic.
• Leading digits are treated as coefficients and are shown at full size.
Numbers that follow an element or a closed parenthesis are converted to
subscripts.
• The equals “=” symbol is converted to a yields “&” symbol.
Notes:
• Equations in a chem box cannot be evaluated or balanced.
• Element capitalization may not work in every situation. For example, to
enter carbon dioxide, CO
2
, you must manually capitalize theO. Otherwise,
typing “co” would result in“Co,” the symbol for cobalt.
