How to name a Compound:
Chemical nomenclature is the term given to classify a compound. Chemists use specific rules to convey different compounds.

Formula's and Names of Binary Non metal Compounds

Binary compounds are chemical compounds that
contains two different elements (ONLY TWO). Ex: Sodium Flouride (NaF) and Magnesium Oxide (MgO).

Rules

Add -ide to the second element.
Use Greek prefixes for # of atoms. (Mono, di, tri, tetra, penta, hexa, hepta, octa, nona, deca)

Examples

Carbon monoxide (CO)
Carbon Dioxide (CO2)
Dinitrogen Pentoxide (N2O5)

Polyatomic ions are ions/compounds that consits of more than one atom.

Examples

Ammonium (NH4+)
Cyanide (CN-)
Hydroxide (OH-)

Binary Acids are compunds that hydrogen is combined with a non metallic atom.

Rule

The prefixes must have -Hydro and the suffixes mustv have an -ic ending.

Examples

Hydroflouric acid (HF)
Hydrochloride acid (HC)
Hydrobromic acid (HBr)
Hydroiodic acid (HI)
Hydro Sulfic (H2S)
