p block elements in inorganic chemistry
Answer (1)
13th Sep, 2021
Dear Student,
The p-block of the periodic table elements consists of the elements of the group-13, group-14, group-15, grup-16, group-17 and group-18 excluding the helium. The group-13 is also called as Boron group. Similarly, group-14 as Carbon group, group-15 as Nitrogen Group, group-16 as Chalcogens, group-17 as Halogens and group-18 as Noble gases. These p-block elements are distinguished by the property that in the atomic ground state, the highest energy electron is a p-orbital.
The p-block elements show a variety of oxidation state both positive and negative. As we go down the group, two electrons present in the valence `s' orbital become inert and the electrons in the `p' orbital are involved in chemical combination. This is known as `inert pair effect'.
Happy Learning!
