Ionic bonds are the bonds between ions. They are formed because of electrostatic attractions. Covalent bonds are formed when atoms are bonded by sharing of electrons. Covalent bonds are the strongest of the three categories of chemical bonds.

Ionic chemistry is the study of matter that is produced when one compound dissolves in water or some other solvent. Ionic compounds are ionic compounds and a base that isn’t electrically neutral. Ions are positively charged, while the electrons are neutral.

The overall charge of the ionic compound must be equal to the charge of the anion minus the charge of the cation. A cation of charge 2+ will only react with an anion of charge -2 when the overall charge of the ionic compound is zero or it is neutral.

If the charge of the cation is greater than the charge of the anion, then the cation will repel the anion and the compound will be stable. When the charge of the cation is less than the charge of the anion, then the anion will repel the cation and the compound will be stable.

Electrons flow from positive to negative. When the electrons flow to an ion that is already bonded, then the bond is broken. When the electrons flow from the anion to the cation, then a bond is formed. If electrons flow in both directions, then the compounds are neutral.

The number of electrons that an atom has is called the valence. To explain the valence number, we would have to explain atomic orbitals.We have to take a look at the periodic table to see what elements can be used to create ionic compounds. Only the elements in the first two rows of the periodic table such as hydrogen and halogens can be used to create ionic compounds.

The valence number tells us how many electrons an atom holds and this is important when we create the formula for ionic compounds. If an ionic compound has a valence number of 8, we can use the 8 negative charges to bond with the positive charge in the cation. For example sodium chloride. Sodium chloride has a valence of 8, and when it bonds with chloride it becomes sodium chloride.

A chemical compound is a solid or liquid compound that contains atoms bonded together. A chemical compound does not contain a molecule of water. A compound contains the molecules of water. A compound is a molecular compound. Molecules of water are not a compound. 827ec27edc
