Hello, It’s time to learn the most important topic of Class 12 Chemistry Chapter “P block Elements” Pdf Download. As we know, this chapter is a part of the inorganic chemistry of class 12 chemistry. You can download the p block elements class 12 chapter notes pdf.
The elements from groups 13 to 18 in the periodic table are p-Block elements. They have a valence shell electronic configuration ns2 np1–6. Since we have already discussed group 13 and 14 elements in the previous class, therefore, we will be covering the remaining groups of p-Block elements in this chapter.

P block Elements Class 12 Pdf Download
Do you know, what are the p block elements of class 12th chemistry?
According to the Book of NCERT, in the P block Elements Chapter, the 15th, 16th, 17th, and 18th groups of modern periodic tables are learned by all of you in this chapter in brief. The definition of P block elements – That element whose electronic configuration is ended with the p sub orbit, are called p block elements. This Chapter is the 7th chapter of the Class 12 Chemistry of NCERT Book.
According to the law of the Modern Periodic table of Elements of General Chemistry. The p block is divided into six groups. All the elements of the P block Elements Class 12 Pdf Download are about non-metals except some. The name of the group of P block elements is such as – Carbon Family, Boron Family, Nitrogen Family, Phosphorus Family, etc.
