Chemistry Unit Three
Nomenclature
| Question | Answer |
|---|---|
| binary compound | chemical compound composed of only two elements |
| binary ionic compound | a salt consisting of only two elements in which both elements are ions, a cation (which has a positive charge) and an anion (which has a negative charge) |
| common name | non-systematic, usesd for naming compounds, not recognized as formal nomenclature; aka trivial |
| type 1 binary compound | binary compound in which the cation has only one form, or charge |
| type 2 binary compound | binary compounds in which the cation can have multiple forms |
| systematic name | name given systematically to compounds. for example: lead(IV)oxide |
| type 3 binary compound | binary compound with two metals |
| polyatomic ion | a charged species ion composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in the context of acid and base chemistry or in the formation of salts |
| oxyanion | chemical compound with the generic formula AxOyz− (where A represents a chemical element and O represents an oxygen atom) |
| acid | substance which reacts with a base and has a pH of less than 7 |
| ion | atom or molecule in which the total number of electrons is not equal to the total number of protons, giving it a net positive or negative electrical charge |
| cation | ion with fewer electrons than protons, giving it a positive charge |
| anion | ion with more electrons than protons, giving it a net negative charge |
| transition metals | all elements in groups three through twelve of the periodic table |
| metals | an element, compound, or alloy that is a good conductor of both electricity and heat. |
