Yes it contains the lead (IV) ion.
If the ion contains only one atom, it is an atom of scandium, for which the most common oxidation state in compounds is +3. However, in gas phase, +2 and +1 are also possible.
No, it doesnot as Potassium has only one positive charge.
The hydroxide ion is -OH.
no
Examples are: PbO, PbNO3, PbCl, PbS, etc.
Mn2P2
Yes it contains the lead (IV) ion.
If the compound contains a polyatomic ion, simply name the ion.
PbCO
PbCO
Mn2O3 =Mn 3+O 2-andMnBr2 =Mn2+Br1-Therefore,The first binary compound (Mn2O3) contains the ion Mn3+
The chromic ion is the chromium (III) ion.
This will depend on the valance of the aluminum ion. The phosphate ion has a -3 oxidation number (PO43-). Some compounds which could be formed: With Al (II) ion - Al3(PO4)2 With Al (III) ion - AlPO4
Iron II nitrate contains an iron ion with a 2+ charge and has the formula Fe(NO3)2. Iron III nitrate contains an iron ion with a 3+ charge and has the formula Fe(NO3)3
+1 . The oxidation number of an ion is always equal to the charge. The silver ion is Ag+ in compounds such as silver chloride. There is also an Ag3+ in compounds such as AgO, which contains Ag+ and Ag3+ in 1:1 proportions, so contains silver with +1 and +3 oxidation numbers and is called silver(I,III) oxide
The iron III ion is Fe3+
