By charge, I assume you mean oxidation number. Oxygen's oxidation number is a very dependable -2, with only a few strange exceptions. A better question would be "What is chlorine's oxidation number in ClO4-?" The answer would be +7.
ClO4 is the perchlorate ion.
Sounds strange but it's right.
This is the perchlorate ion, with a charge of -1
The conjugate acid of ClO4- ion is perchloric acid HClO4.
The charge of Cl04 is 1.
ClO2- is the chlorite ion.
chlorine dioxide
The charge of O2 in ClO4- is -8.
it's -1
Hclo4
ClO4 is polar.
Mg(ClO4)2
3 moles of (ClO4)3- and 1 mol AlAluminium perchlorate is Al)CLO4)3.10H2O.
hyperchlorate is not to be confused with hypochlorite. hyperchlorate is usually called perchlorate and is the ClO4- ion. Calcium has a 2+ charge so that would make Calcium hyperchlorate Ca(ClO4)2. Hyperchlorate is a very cool ion because it can create very energetic reactions.

The answer is Cd(ClO4)2 The charge of cadmium(II) is 2+, and the charge of ClO4 is 1-. So to even the charges we must have two of the ClO4.
ClO4 is polar.
The formula is ClO4-
The overall charge is -1. Oxidation number of oxygen in -2. By balancing the charges, chlorine is in +7 state.
The overall charge is -1. Oxidation number of oxygen in -2. By balancing the charges, chlorine is in +7 state.
mg(clo4)2
+7 for Cl and -2 for O in ClO4- ion
Cu(ClO4)2 ==> Cu^2+ and 2ClO4^-
ClO4 is polar.
generally negatively charged chloride ion. but there are a few species where chlorine has positive charge like ClO3-, ClO4- etc.
The perchlorate ion has one available bond.
The molar mass of the perchlorate ion, ClO4- , is 99.44 grams.
