Non metal ions:
N3- - nitride ion
P3-- phosphide ion
O2- -- oxide ion
S2--- sulfide ion
Cl- -- chloride ion
I- -- iodide ion
F--- fluoride ion
Br- -- Bromide ion
*********************
charges on ions
Cr3+, Cr2+, Cr6+
Fe3+ , Fe2+
Co2+, Co3+
Cu2+,Cu+
Pb2+,Pb4+
Mn2+, Mn4+, Mn7+
Ni2+, Ni4+
Sn2+, Sn4+
********************
when the sum of charges of positive ions are equal to sum of charges of negative ions. in compound ,it is said to
be charge balanced
chemical formula
Iron(2) chloride = FeCl2
Iron(3) chloride = FeCl3
Copper(1)sulfide = CUS
copper(2) chloride = CuCl2
Tin(2) Chloride = SnCl2
Tin(4) chloride= SnCl4
***********************
All solved . Thank you!
