No, it is not true that a neutral ionic compound can only contain ions with identical charges. You can have, for example, a compound that consists of twice as many positive ions as negative ions, but the positive ions have only half the charge; +1 ions bonded to -2 ions. There are many different possible ratios with which different elements or radicals combine. As long as the total amount of charge adds up to zero, you still have a neutral ionic compound.

What is the difference between type one binary compound and type two binary compound?
Type one binary compounds have a cation (+ charge) that has only 1 possible oxidation state, for example sodium (Na^1+). In type 2 binary compounds, the cation can have more than one oxidation state, for example iron which can be 2+ or 3+.
Is a compound held together by opposite charges?
Ionically bonded compounds are held together by opposite charges on the anions and cations that constitute the compound. Covalently bonded compounds and metals are held together by other means.
What is the oxidation number of HClO2?
In oxyacids, oxygen is always taken to have an oxidation state of -2 and hydrogen to have an oxidation state of +1. Therefore, in this compound, chlorine must have an oxidation state of +1 for the charges to balance.
What is the oxidation number of N in CuCN?
Nitrogen's oxidation number is -4.Carbon's oxidation number is +3.The cyanide ion has -1 charge. Nitrogen is in -3 state. By balancing the charges: the oxidation number of carbon is +4.
The charges in a compound should always add to?
By definition, a compound is always neutral. If the polyatomic chemical entity has a charge, it is no longer a compound, but is now a polyatomic ion. Ionic compounds and molecular compounds are also neutral in charge. The word "ionic" is just referring to the type of chemical bond in the molecule.
What determines whether a compound will dissolve in whether?
The polarity or charges of compounds will determine if a compound would dissolve in water, where compounds with opposite charges within their molecules dissolve in water.
In molecular compounds are the total number of positive charges equal to the total number of electrical charges?
yes. molecular compound is neutral. if a compound has charges, that's known as ionic compound.

How do you find the oxidation numbers?
For a neutral atom or compound, the oxidation number is always 0. For an ion, the overall oxidation number is its charge. If you need to find an oxidation number to a particular atom of a compound, there are two ways: working out the Lewis structures or balancing the charges.

What is the common oxidation numbers or charges for selenium?
0 in elemental form. -2 is most common in its compounds (selenides)
In the compound Al2O3 aluminum has an oxidation number of 3 while oxygen's oxidation number is .?
In the compound Al2O3, aluminium has an oxidation number of +3, while oxygen's oxidation number is __-2 ____. For aluminium oxide (Al2O3) to form the ionic charges MUST balance. Hence For the 2 aluminiums it is 2 x 3 = +6 For the 3 oxygens it is 3 X -2 = -6 +6 -6 = 0 So the charges balance, hence Al2O3 is neutrally charged compound and NOT an ion.

Nitrogen's oxidation number is -4.Carbon's oxidation number is +3.The cyanide ion has -1 charge. Nitrogen is in -3 state. By balancing the charges: the oxidation number of carbon is +4.
When writing compound names do you need a charge?
No, compounds do not carry electrical charges, ions do.
