Exercise 2.2 Mineral groups; Most minerals are made up of a cation (a positively charged ion) or several cations, plus an anion (a negatively charged ion (e.g., S 2−)) or an anion complex (e.g., SO 4 2−). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3+ (iron) and the anion is O 2− (oxygen). The two Fe 3+ ions have an overall charge of …

2.2.3 Moles. A mole of an element (or of a compound) is defined as containing 6.022 × 10 23 atoms (or molecules). The number, 6.022 × 10 23, is known as Avogadro's number. So, one mole of carbon is equivalent to 6.022 × 10 23 carbon atoms. The scale used to measure atomic mass has changed slightly over time.
