Substances that consist of covalent molecules are usually gases or liquids at room temperature. Ionic bonds are formed between a metal and non-metal, for example, sodium chloride. Outer electrons ...

The formula of a covalent network or ionic compound gives the simplest ratio of atoms/ions in the substance. Sometimes the name of the compound gives information about the formula of that compound.

A little water helps expose the sodium so it can react with the chlorine gas. The reaction releases a lot of heat as the ionic compound sodium chloride is formed. A sodium and chlorine atom are near ...

Covalent chemical probes – chemical probes that form a covalent bond with their target biomacromolecule(s) represent powerful tools that can be used for biology discovery, target validation (or ...

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...
