nomanclature

Naming of ionic and covalent compounds

Covalent NCl2

Nitrogen Dicloride

Transition metals( Def)

A bond between a transition metal and nonmetal. To do the nomanclature you have to find the charge by finding the amounts of each atom and then multiplying the antion by the charge then the amount of the cations to make a charge that 0's out

Binary compounds (definition)

A bond between two nonmeatals

Acetate

CH3COO/ -1

Cyanide

CN/-1

Carbonate

CO3 2-

Hypochlorite

ClO/-1

Chlorite

ClO2/-1

Chlorate

ClO3/ -1

Perchlorate

ClO4/ -1

Transition metals Ex: PbO2

O- 2(amnt of atoms)x4(charge) = 4 Pb- 1(amnt of atoms)x(variabe x charge)= 4 so x= 4 So then we take the 4 and attach it to our nomanclature Lead(IV)Oxide
