Explanation:

It is known that ionic compounds are formed by transfer of electrons from one atom to another. And, during this type of bonding there occurs long range of bonding structure due to the nature of ionic bonds.

As these also contain opposite charge hence, they are more tightly packed with each other.

Whereas in covalent bonding the atoms tend to share electrons due to which they are not tightly packed with each other. As a result, empty spaces are created between the bonding structure which tends to reduce the density of the material.

Therefore, covalently bonded materials generally less dense than metallically or ionically bonded ones.

The group 17 elements of the periodic table have 7 valence electrons and are highly reactive, with low melting and boiling points. The halogens - including fluorine, chlorine and bromine - have a common tendency to form salts, but they are all of a toxic nature.

Explanation:

We can say that Chemical reaction is a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds.

A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.

See attachment for the buffer of the chemical reaction.
