An atom with a -1 charge is a negatively charge ion (anion) and has has one more electron than it has protons. The most common -1 ions are the halide ions.
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.
An ion is always electrically charged.
The ion with the formula SO4 and a -2 charge is called sulfate ion. It consists of one sulfur atom and four oxygen atoms with a total charge of -2.
When Te forms an ion in a compound, it typically has a charge of -2.
Magnesium as an atom has two valance electrons. To complete it's octet, it must lose two electrons. Losing two electrons will make Mg have 12 protons and 10 electrons therefore having a +2 charge.
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
The charge on the lead ion (Pb) in PbS2 is +2. This is because each sulfur atom (S) has a charge of -2, and since there are two sulfur atoms for every lead atom in lead(IV) sulfide (PbS2), the lead ion must have a charge of +2 to balance out the charges in the compound.
The ion charge on sulfate is 2-. This means that the sulfate ion carries a charge of -2.
The charge on ion X in X2O3 is +3. This is because the overall charge of the compound is neutral, and there are three oxygen atoms each with a charge of -2, so the X ion must have a charge of +3 to balance it out.
The charge is minus 2.
The oxidation number of Zn in the complex ion Zn(OH)4 2- is +2. This is because the overall charge of the complex ion is -2, and each hydroxide ion (OH-) has a -1 charge. Hence, the zinc (Zn) ion must have a +2 charge to balance the overall charge of the complex ion.
The charge on lead in the compound Pb(NO2)2 is +2. This is because each nitrite ion (NO2) has a charge of -1, and there are two nitrite ions binding to the lead ion, therefore the lead ion must have a charge of +2 to balance the -2 charge from the nitrite ions.
Sulfur monoxide is a gaseous compound, NOT an ion; hence it has NO charge.
The charge of an NO ion is -1. This is because nitrogen typically has a charge of +5 and oxygen typically has a charge of -2, resulting in a charge of -1 for the NO ion.
strontium is a metal, therefore it must form only positive ions.
Iron can acquire a charge of +2 or +3 as an ion. The +2 charge is more common and is known as ferrous ion, while the +3 charge is less common and is known as ferric ion.
