Naming Chemical Compounds Ionic Compounds Ionic Compounds Monatomic

Ionic Compounds • Monatomic cations – Mono means 1 – Cations are + metal

Ionic Compounds • Monatomic anions – Mono means 1 – Anions are – non-metal

Naming Chemical Compounds Ionic Compounds

Ionic Compounds • Monatomic cations – Mono means 1 – Cations are + metal ions – Remember

Ionic Compounds • Monatomic anions – Mono means 1 – Anions are – non-metal ions

Naming Ionic Compounds • Name the cation (monatomic or polyatomic), add Roman Numeral if a transition metal • Add the suffix –ide to the anion if monatomic. Name the Polyatomic. Bond, Ionic Bond I didn’t Catch your name.

Ionic Compounds • Polyatomic ions – Poly- means many or more than one – These are two or more atoms bonded together with an overall charge – Most polyatomic ions are negative

Naming Compounds • -ite GOT –ate • -ate endings have one more oxygen (O) than –ite endings. • NO 2 -1 nitrite NO 3 -1 nitrate • SO 3 -1 sulfite SO 4 -1 sulfate

Hydrates (Water) • Hydrates simply means that one or more water molecules are attached • Name the ionic compound • Use prefixes to tag the # of water molecules

Practice Naming Hydrates • • • Cu. SO 4 * H 2 O Copper (II) Sulfate Monohydrate Na 2 CO 3 * 6 H 2 O Sodium Carbonate Hexahydrate Ca 3(PO 4)2 * 2 H 2 O

Naming Acids • All acids are characterized by beginning their molecular formula with the hydrogen (H) atom. • HCl, H 2 SO 4, HNO 3, HI, HF, HC 2 H 3 O 2 • That is because a H+ is given off when it is dissolved (disassociates) in water.

Naming Acids • We will use the prefix hydro- and suffic –ic if the anion ends in –ide • HCl hydrogen chloride would be hydrochloric acid • HF • HI • HBr

Naming Acids • Acids that end with the suffix –ate. • Replace with the –ic suffix • HNO 3 hydrogen nitrate • Nitric Acid • Just remember, I –ate something –ic(y).

Naming Acids • Acids that end with the suffix –ite. • Replace with the suffix –ous. • HCl. O 2 hydrogen chlorite • Chlorous acid • –ite is said by –ous.

Let’s Practice • • HCl H 2 SO 4 HNO 3 HNO 2 HC 2 H 3 O 2 H 2 CO 3 HF
