zero
Compounds can have a neutral charge, a positive charge (cation), or a negative charge (anion), depending on the distribution of electrons within the atoms that make up the compound.
All compounds have a net charge of zero since they are composed of positively charged protons and negatively charged electrons that balance each other out to maintain electrical neutrality.
Strictly, all compounds have no charge. What would be a compound if neutral but actually has a charge should properly be called an ion. Some compounds, such as the diatomic molecules of the elements hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine, have perfectly symmetrical covalent bonds without even any polarity. Most covalent bonds between dissimilar atoms have some polarity, as do all ionicly bonded compounds, but this does not mean that the compounds themselves have net electrical charge.
Compounds can be charged by different methods. But naturally most of the compounds are uncharged. So the overall charge of most compounds is neutral.
There is no charge. All compounds are electrically neutral. If you mean the charges of the component ions, copper carries a 2+ charge and the hydroxide ions carry a 1- charge.
Oxide ions have a charge of -2.
Some compounds have a charge. It depends on the charges of the components of the compound. For example, NO3- has a charge of -1 because the charge of its components are each O is 2- and the N is 5+,..
Ionic compounds are typically made up of a metal cation and a non-metal anion. The metal cation provides the positive charge, while the non-metal anion provides the negative charge. So, while not all ionic compounds contain a metal, they often do.
In ionic chlorine compounds, the ionic charge of chlorine is -1.
Oxygen typically has a charge of -2 when it forms compounds.
positive
Chemical compounds must have a net charge of zero. This is achieved by balancing the positive and negative charges of the atoms that make up the compound, ensuring that the total positive and negative charges cancel each other out.
