Chapter: 12th Chemistry : p-Block Elements-II

Group 15 (Nitrogen group) elements

In this unit we learn the remaining p-block groups, pnictogens, chalcogens, halogens and inert gases.

p-BLOCK ELEMENTS – II

 

INTRODUCTION

We have already learnt the general characteristics of p-block elements and the first two group namely icosagens (boron group) and tetragens (carbon group) in the previous unit. In this unit we learn the remaining p-block groups, pnictogens, chalcogens, halogens and inert gases.

 

Group 15 (Nitrogen group) elements:

 

Occurrence:

About 78 % of earth atmosphere contains dinitorgen (N2) gas. It is also present in earth crust as sodium nitrate (Chile saltpetre) and potassium nitrates (Indian saltpetre). The 11th most abundant element phosphorous, exists as phosphate (fluroapatite, chloroapatite and hydroxyapatite). The other elements arsenic, antimony and bismuth are present as sulphides and are not very abundant.

 

Physical properties:

Some of the physical properties of the group 15 elements are listed below
