-2
An ion is always electrically charged.
The charge of each titanium ion in the ionic compound TiO2 is +4. This is because oxygen typically has a charge of -2, so in order for the compound to be neutral, titanium must have a charge of +4 to balance out the -2 charge of each oxygen ion.
The charge on CrCl3 is 0, since it is a neutral compound. Each Cl ion has a charge of -1, meaning that three Cl ions combine with one Cr ion with a charge of +3 to form the compound with an overall charge of 0.
Tellurium (Te) has an atomic number of 52, meaning it typically has 52 electrons when neutral. When it forms an ion, the number of electrons changes based on its charge. For example, if Te forms a -2 ion (Te²⁻), it would have 54 electrons, while if it forms a +4 ion (Te⁴⁺), it would have 48 electrons.
The charge on the copper ion in Cu3P is +1. This is because the overall charge for the compound Cu3P is 0, and since there are three copper ions present, each copper ion must have a charge of +1 to balance the -3 charge of the phosphorus ion.
The charge of the sulfate ion (SO4) in a chemical compound is typically 2-.
Sulfur monoxide is a gaseous compound, NOT an ion; hence it has NO charge.
The charge on the copper ion in CuF2 is +2. This is because fluorine typically has a charge of -1, and there are two fluorine atoms in the compound which balances out the charge of the copper ion.
There is no iron ion in SCl3. The charge on the scandium ion is 3+.
The ionic compound formed from NaH2PO4 is sodium dihydrogen phosphate. In this compound, the sodium ion has a +1 charge, and the dihydrogen phosphate ion (H2PO4-) has a -1 charge.
An ion is always electrically charged.
The compound PbI4 is lead (II) iodide, where the lead ion has a charge of +2 and the iodide ion has a charge of -1.
The charge on a chloride ion in any ionic compound is -1. AlCl3 is usually considered an ionic compound, although it has some covalent character in its bonds also. If the compound is considered covalent, the characteristic number for a particular atom within the compound is usually called "oxidation number" or sometimes "formal charge" instead of simply "charge", but that is also -1.
It must be equal to the charge on the compound/ion
The bromide ion has a charge of -1. In the ionic compound potassium bromide (KBr), potassium has a charge of +1 to balance the -1 charge of the bromide ion.
NL3, which represents the compound nitrogen trilithide, is an ionic compound. It contains the nitrogen ion with a -3 charge and the lithium ion with a +1 charge.
The charge of each titanium ion in the ionic compound TiO2 is +4. This is because oxygen typically has a charge of -2, so in order for the compound to be neutral, titanium must have a charge of +4 to balance out the -2 charge of each oxygen ion.
