describe the nature of the compoundsformed when chlorine, bromine and iodine react with metals andnon-metals

When chlorine, bromine, and iodine, which are all halogens, react with metals, they form metal halides. These are ionic compounds, which means they are made up of positive and negative ions. The metal acts as the positive ion (or cation), while the halogen acts as the negative ion (or anion). These compounds are typically solid at room temperature and have high melting and boiling points due to the strong ionic bonds between the ions. They also tend to be soluble in water and other polar solvents.

For example, when chlorine reacts with sodium, it forms sodium chloride (NaCl), which is common table salt. The reaction is as follows:

2Na(s) + Cl2(g) -> 2NaCl(s)

When these halogens react with non-metals, they form covalent compounds. These compounds are formed by the sharing of electrons between the halogen and the non-metal. These compounds tend to have lower melting and boiling points compared to ionic compounds, and they may be gases, liquids, or solids at room temperature. They are also less likely to be soluble in water.

For example, when chlorine reacts with hydrogen, it forms hydrogen chloride (HCl), which is a gas at
