1
Q

nomenclature naming rules

A
  • 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
2
Q

naming examples

A
  • Nal - iondine - sodium iodide
  • K_2S - ptoassium sulfide
  • MgS - magnesium sulfide
  • HCl - hydrogen chloride
  • Ca_2C - calbium carbide
  • SrO - strontium oxide
3
Q

naming oxyanions of nitrogen and sulfur

A
  • 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
4
Q

naming of Oxyanions of CHlorine

A
  • CIO^- - hypochlorite
  • CIO_2 ^- - chlorite
  • CIO_3^- chlorate
  • CIO_4^- perchlorate
  • BrO_3^- = bromate
  • IO_3^- = periodate
5
Q

polyatomic ions in compounds

A
  • 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
6
Q

polyatomic naming examples

A
  • NA_2SO_4 - sodium sulfate
  • NH_4Cl - ammonium chloride
  • Ba_3(PO_4)_2 - barium phosphate
7
Q

common and systematic for transition metals

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