Nomenclature
Nomenclature- how to name things
naming compound
1.) metals/nonmetals (Type 1 and Type 2)
2.) contain 2 nonmetals (Type 3)
Type 1/Type 2
Type 1- metas with one type of charge - ends in -ide
Type 2- two or more cations that have different charges (middle section aka Transition Metals)
Examples:
FeCl2 - type 2
Na2O - type 1
BaCl2 - type 1
ZnO - type 2
Au3N - type 2
naming compound
1.) metals/nonmetals (Type 1 and Type 2)
2.) contain 2 nonmetals (Type 3)
Type 1/Type 2
- Binary ionic compound- contains a positive ion (cation) and a negative ion (anion)
Type 1- metas with one type of charge - ends in -ide
Type 2- two or more cations that have different charges (middle section aka Transition Metals)
Examples:
FeCl2 - type 2
Na2O - type 1
BaCl2 - type 1
ZnO - type 2
Au3N - type 2
Type 1
Rubidium Bromide Rb Br Rb +1 Br -1 RbBr |
Type 2
Iron(II) Chloride 2/1=2 -1*2=-2 FeCl2 |
Type 3- specifically 2 non metals
Prefixes
Mono = one
Di = two
Tri = three
Tetra = four
Penta = five
Hexa = six
Hecta = seven
Octa = eight
Examples:
N2O5- dinitrogen pentaoxide
P4O6- tetraphosphorus hexaoxide
dinitrogen trioxide- N2O3
***Exceptions:
Aluminum (3+), Zinc (2+), and Silver (+) are Type 1
- First element is named first- full element name is used
- second is named like an anion
- prefixes to denote the number of atoms except "mono"
