Representative elements: Elements belonging to the s and p-blocks in the periodic table are called the representative elements or main group elements. In p-block elements, as we go down the group, two electrons present in the valence s-orbital become inert and are not available for bonding (only p-orbital involves chemical bonding). This is also a product of carbon. It is combustible and supports combustion. Understand their properties, electronic configurations, analogous behaviour and diagonal relationships. The solubilities of these salts further increase on descending the group. Previous Year Papers. In presence of moisture it gives PH, - It crystallises as deliquescent white solid, Fertilizers are the chemical substances which are added to soil in order to make up the deficiency of nutrients required by plants. Uses of the P-block Elements. Class 10 Class 12. It is also called boron family.
