• Chemical elements present some unusual exceptions to normal rules for usage of indefinite articles (a and an)
• Choose the article based on the sound of the element when sounded out fully (e.g., 'silver' not 'Ag')
• For isotopes, consider the sound of the element symbol first

This article discusses different ways to format SI units in a manuscript.

• There are several types of prefixes used for chemical compounds, including numerals, Greek letters, and structural prefixes.
• Hyphens are used extensively; there should not be any space on either side of the hyphen.
• Some prefixes are capitalized, while others are not.

• Some chemistry conventions are unique when compared with writing about other sciences.
• In particular, take care to report volume and/or mass of key reagents and to capitalize compounds appropriately.

• Capitalization rules for chemical compounds and abbreviations can be confusing.
• At the beginning of a sentence, capitalize the first syllabic portion of the compound name.
• Chemical elements and amino acids are not capitalized within a sentence, just their symbol (e.g., Ag or Gln).
