A
The charge of the lead ion in the compound lead phosphate, Pb3(PO4)2, is 2+.
a positive sign in an atom symbol denotes an ion, for example, Fe2+
Fe3- represents an ion of iron with a 3- charge. The symbol "Fe" refers to the element iron, and the superscript "-3" indicates that the ion carries a negative charge of 3. The 3- charge means that the ion has gained three electrons to achieve a stable configuration.
This is the electrical charge of the ion.
This is the ion Th4+
A
Pb2+
The formula for a chromate ion is CrO4-2, and its charge is -2.
Lead iodide is not a correct name. Lead is a transition metal and can form more than one ion. The charge of the lead ion should be in the name. For example, lead(II) iodide, which would be PbI2. Lead(IV) iodide would be PbI4.
Carbon's symbol is C. A carbon atom has no charge, but a carbon ion has a +2 charge.
The chromate ion has a charge of 2-. Its symbol is CrO42-.
The phosphide ion has a charge of 3-. Its symbol is P3-.
Pb4+
The formula, including the charge, for a chromate ion is CrO4-1.
Lead being a transition metal has two possible charges: +2 or +4.
It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.
