Metal+Non Metal Binary
Compounds
X transition metal)
Formula to name (non
Use this first name in the formula and end the
second name with -ide.
Ex: NaCl ----> Sodium Chloride
Name to formula (non transition metal)
1. Find the charges associated with the elements
and criss cross them.
Ex: Magnesium Chloride ‐‐‐‐> Mg+2 Cl‐1 ‐‐‐MgCl2 Name to formula (transition metal) 1. Take the Roman numeral and make it into a positive superscript (exponent) 2. Then find the charge for the second element. Then criss cross. +2
Nonmetal + nonmetal
a) name the first element b) use the stem of the second element; add '‐ide" c) precede each name with a prefix to indicate the number of each kind of atom. Example: N2O4 ‐‐ dinitrogen tetroxide SO3 ‐‐ sulfur trioxide Naming Binary Compounds ‐ Prefixes Used for Two Non‐metals Prefix Example *mono‐ (one) CO ‐ carbon monoxide di‐ (two) CO2‐ carbon dioxide tri‐ (three) N2O3‐ dinitrogen trioxide tetra‐ (four) CCl4‐carbon tetrachloride penta‐ (five) N2O5‐dinitrogen pentoxide hexa‐ (six) UF6‐uranium hexafluoride ‐1
Ex: Iron (II) Bromide‐‐‐> Fe Br ‐‐‐> FeBr2 Formula to name (transition metal) Hepta (seven) IF7 Iodine heptaflouride 1. Reverse criss cross. Octa (eight) 2. **Write the name of the first element with the Roman numeral. Nona (nine) Trinitrogen nonaoxide N3O9 3. Write the name of the second element with “ide” at the end of it Ex: Au3N2 ‐‐‐> Au +2 N‐3 ‐‐‐>Gold (II) Nitride **Some transition metal do not require a roman numeral bases on them only having one type of ionized atom Example Zn, Ag. tetrasulfur octachloride S4Cl8 Deca (ten) dioxygen decabromide O2Br10 *You will NEVER start with mono. Example CO2 is carbon dioxide NOT monocarbon dioxide
