Chemical Bonding - Ions and Metals: Names of Ions and Ionic Compounds

Question 1

nomenclature naming rules

Answer 1

• ionic compounds: cation and anion
• cations are named exactly the same as the metal they came from
• simple monoactomic anions are named by adding the suffix -ide to root names from nonmetals

Question 2

naming examples

Answer 2

• Nal - iondine - sodium iodide
• K_2S - ptoassium sulfide
• MgS - magnesium sulfide
• HCl - hydrogen chloride
• Ca_2C - calbium carbide
• SrO - strontium oxide

Question 3

naming oxyanions of nitrogen and sulfur

Answer 3

• SO_3^2- - sulfite
• NO_2^- - nitrate
• SO_4^2- - sulfate
• NO_3^- - nitrate
• in each case the N or S with fewer atoms of oxygen has the ending -ite

Question 4

naming of Oxyanions of CHlorine

Answer 4

• CIO^- - hypochlorite
• CIO_2 ^- - chlorite
• CIO_3^- chlorate
• CIO_4^- perchlorate
• BrO_3^- = bromate
• IO_3^- = periodate

Question 5

polyatomic ions in compounds

Answer 5

• if more than one polyatomic ion required it is grouped with parenthesis and number indicated with a subscript
• MG^2+ + )H^- –> Mg(OH)_2
• NH_4^+ + PO_4^3- –> (NH_4)_3 PO_4
• CA^2+ + NO_3^- –> CA(NO_3)_2

Question 6

polyatomic naming examples

Answer 6

• NA_2SO_4 - sodium sulfate
• NH_4Cl - ammonium chloride
• Ba_3(PO_4)_2 - barium phosphate

Question 7

common and systematic for transition metals

Answer 7

• ous - lower oxidation state
• cuprous - Cu(I)
• ferrous - Fe(II)
• ic - higher oxidation state
• cupric - Cu(II)
• ferric - Fe(III)
