What is the sume of cation values and anion values in an ionic compound?
In an ionic compound, the sum of the cation values is equal to the sum of the anion values. This is because ionic compounds must have a neutral charge overall, which is achieved by balancing the positive charge of the cations with the negative charge of the anions.
What is true about the sum of all oxidation numbers?
For a neutral molecule it is zero, for polyatomic ions the sum is the same as the ionic charge.
Sum of all oxidation numbers in a compound?
The sum of oxidation numbers in a compound is zero for a neutral compound and equal to the charge of the ion for an ionic compound. This rule stems from the fact that the total charge of a compound must be zero for a neutral compound and must balance out for an ionic compound.
What must the sum of the oxidation number be equal to?
It must be equal to the charge on the compound/ion
What is the overall charge of an ionic compound?
it is always equal to zero.The overall charge of a formula unit for an ionic compound is zero. The numbers of positive and negative ions are such that the sum of the positive charges and the negative charges is zero.

What is the sum of the charges of all the cations and anions?
The sum of the charges of ions in an ionic bond is always equal to zero. The compound would consist of the minimum number of ions necessary to make the charge of the compound equal to zero.For example, the charge of Na is +1, and the charge of Cl is -1. When these are bonded in an ionic bond, the Na+ and Cl- make NaCl, with a charge of zero.When you have two elements that aren't equal in charge, then you must make it to where the charges of both the cations and the anions equal zero when summed. You do this by adding more cations and anions to the compound as necessary.For example, the charge of Magnesium is +2, and the charge of Nitrogen is -3. To make the charge of this compound equal zero, you would need three Magnesiums and two Nitrogens. (2+2+2-3-3=0.) This means that when Mg2+ and N3- are bonded in an ionic bond, they would make Mg3N2.But basically, the short answer is that the sum of the charges on the ions in a unit of a compound is zero.

What is the overall charge of an ionic compound?
it is always equal to zero.The overall charge of a formula unit for an ionic compound is zero. The numbers of positive and negative ions are such that the sum of the positive charges and the negative charges is zero.
Why ionic compounds are neutral as a whole?
The total positive charge of the cations in an ionic compound is balanced by a total negative charge of equal magnitude from the anions.
When the equation is correctly balanced the sum of the total charge of the reactants is?
When the equation is correctly balanced, the sum of the total charge of the reactants is equal to the sum of the total charge of the products. This ensures that the law of conservation of charge is upheld in the chemical reaction.
How is oxidation number determined for ionic compounds?
In ionic compounds, the oxidation number is determined by the charge associated with each ion. For cations, the oxidation number is the same as the charge on the ion. For anions, the oxidation number is the negative of the charge on the ion. The sum of the oxidation numbers in an ionic compound must be zero.
In a polyatomic ion the algebraic sum of the oxidation numbers of all atoms is equal to?
The algebraic sum of the oxidation numbers of all atoms in a polyatomic ion is equal to the overall charge of the ion.
What is the sum of all charges in the formula for an ionic compound?
The sum of all charges in the formula for an ionic compound must be zero. This is because the compound is made up of positively and negatively charged ions that combine in such a way that the overall charge is neutral.
Why ionic compound is neutral?
Ionic compounds are neutral overall because they consist of positively charged cations and negatively charged anions that balance each other out. The total positive charge from the cations is equal to the total negative charge from the anions, resulting in a neutral compound.
