Naming Ionic Compounds I didn’t Catch your name. 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

Writing Ionic Compounds Take the charge number on metal make it subscript on non-metal Take the charge on the non-metal and make it subscript on metal ALWAYS REDUCE

Naming Acids All acids are characterized by beginning their molecular formula with the hydrogen (H) atom. HCl, H2SO4, HNO3, HI, HF, HC2H3O2 That is because a H+ is given off when it is dissolved (disassociates) in water.

Naming Acids Acids that end with the suffix –ate. Replace with the –ic suffix HNO3 hydrogen nitrate Nitric Acid Just remember, I –ate something –ic(ky).

Naming Acids Acids that end with the suffix –ite. Replace with the suffix –ous. HClO2 hydrogen chlorite Chlorous acid –ite is said by –ous.

Naming Acids We will use the prefix hydro- and suffic –ic if the anion ends in –ide If it ends in –ide put hydro- (d=d) HCl hydrogen chloride would be hydrochloric acid HF HI HBr

Prefixes Mono-1 Di-2 Tri-3 Tricycle has 3 wheels Tetra-4 Penta-5 Pentagon has 5 sides Hexa-6 six has an x and so does hexa- Hepta-7 Octa-8 Octopus has 8 arms Nona-9 Nona- and Nine begin with N’s Deca-10 Remember 10 years in a decade

Naming Molecular Compounds Rules are the same for naming the first and second atoms. There are no polyatomic ions or Roman numerals. Remember, Molecules are two non-metals Prefixes are added to the beginning of the atoms name according to its subscript # The prefixes are the same as for the hydrates

Let’s Practice HCl H2SO4 HNO3 HNO2 HC2H3O2 H2CO3 HF
