Concept introduction:
The group-17 of the periodic table is also called as halogens. They are most reactive and most electronegative non-metals. The reactivity and electronegativity of elements decreases down in the group. The F atom is most electronegative in nature, it forms a weak acid with hydrogen.

Concept introduction:
The group-17 of the periodic table is also called as halogens. They are most reactive and most electronegative non-metals. The reactivity and electronegativity of elements decreases down in the group. In other words; in displacement reactions, a more reactive halogen can displace a less reactive halogen to form product. For example, chlorine can displace bromine from its solution but vice-versa is not possible. The reactivity order for halogens is:

Concept introduction:
Ammonia
A species can act as a base if it accepts hydrogen ion from the solution or donate hydroxide ion.
