Chemistry that promotes the design and application of chemical products and processes that are compatible with human health and that preserve the environment. (Section 18.5)

Electrically charged atom or group of atoms (polyatomic ion); ions can be positively or negatively charged, depending on whether electrons are lost (positive) or gained (negative) by the atoms. (Section 2.7)

Compounds formed from a molecule of phosphoric acid, a sugar molecule, and an organic nitrogen base. Nucleotides form linear polymers called DNA and RNA, which are involved in protein synthesis and cell reproduction. (Section 24.10)

The gain of electrons. Alternatively, either the gain of hydrogen, loss of oxygen, or both

A method that chemists use to deal with the inadequacy of bond-line drawings.

Rules for predicting the wavelength of maximum absorption for a compound with extended conjugation.
