Nomenclature

Nomenclature. The language of chemistry. Step 0: Identify the Type of Compound. Look at the left side of the name or formula If the left-most element is a Transition metal, then the compound uses the stock naming system.

Molecular Formula

Molecular Formula. Percent Composition ? Empirical Formula. The percent composition of fuel is 81.7% carbon and 18.3% hydrogen. What is the empirical formula of the fuel? Start by assuming 100 g of the compound (81.7 g) / (12.01 g/mol) = 6.80 mol C (18.3 g) / (1.008 g/mol) = 18.2 mol H.

Molecular Compounds

Molecular Compounds. Molecular Compounds. Molecular Compounds form between nonmetals and nonmetals. (ex. S 2 O 4 ) Covalent bonds form when atoms share electrons. Neither atoms gain or lose electrons because their electronegativity values are very close.

Aim: How to distinguish between ionic and covalent bonding?

Aim: How to distinguish between ionic and covalent bonding?. Two major categories of compounds are ionic and molecular (covalent) compounds. Metals tend to react with nonmetals to form ionic compounds. Nonmetals tend to react with other nonmetals to form molecular (covalent) compounds.

Naming Covalent Molecules

Naming Covalent Molecules. JUST like ionic, but use prefixes. Put a prefix in front of the ion name (except if it is mono- for the first element, then just leave it off) CF 4 = carbon t etra fluoride CO 2 = carbon di oxide N 2 H 4 = di nitrogen tetra hydride
