Oxisales

• Traditional nomenclature: is named similarly to the acid oxoacid from which proceeds by replacing the termination-bear  by -ito and termination -ico by -ato followed by the metallic element completed at:

• -ico (if it has a Valence)• -bear, - ico (if you have 2 valences)• hiccups... bear - bear, - ico (if you have valences)•

hiccups... bear - bear, - ico, per... ico (if you have ! valences)• Stock nomenclature: is named similarly to the traditional nomenclature followed by the metallic element indicating the

valencia which acts in "oman numerals in parentheses.• Systematic nomenclature: is named with the name of the anion followed by the name of the cation and followed by

the prefix indicating the number of atoms of the metallic element. #here the anion is in parentheses, the number of ionsis indicated by the $ree% prefixes:

• 2: &is -• 'or : ris -• !: etra%is -

• : *ent+%is -• : exa%is -• : e ta%is -
