Study Notes
Chemical Compounds
-
Compounds consist of two or more elements in a definite ratio.
-
Empirical Formula: Shows the simplest ratio of elements in a compound.
-
Molecular Formula: Shows the actual number of atoms of each element in a molecule.
Dihydrogen Monoxide
-
A clever science fair experiment tested public perception of chemicals.
-
Dihydrogen monoxide (H2O) was presented as a dangerous substance, resulting in 86% of participants voting to ban it.
-
This highlights the importance of understanding chemical nomenclature and properties.
Inorganic Chemical Nomenclature
-
Cations: Positively charged ions formed by loss of electrons from a neutral atom.
-
Naming Cations:
- Add "ion" to the element name for common cations.
- Use Stock numbers (Roman numerals) to indicate charge for metals with multiple cationic forms.
- Older nomenclature used "ous" and "ic" endings.
-
Anions: Negatively charged ions formed by the gain of electrons from a neutral atom.
-
Naming Anions:
- For monoatomic anions, add "ide" to the stem of the element name.
- Oxanions:
- Use "ate" ending for the most common form.
- Use "ite" ending for one less oxygen than the "ate" form.
Naming Ionic Compounds
- Name the cation first followed by the anion.
- Omit the word "ion" in the name.
- Prefixes are not used to indicate the number of anions.
Multi-Vitamin Preparations
