NCERT Solutions for Class 12 Chemistry Chapter 7 The P Block Elements


P-block' elements are primarily found on the right side of a periodic table. Elements like boron, carbon, nitrogen, Oxygen, etc. are called p-block elements. The reason that they are called so is that their valence electrons are present in the p-orbital. The chemistry of inorganic ring systems of the p-block elements has a long and venerable history that dates back to the early 19th century. The elements of Group 13, 14, 15, 16, 17 and 18 are called P block elements. The general outer electronic configuration ns2np1-6 represents them. P block elements exist in all the three physical states and maybe metals, non-metals or metalloids. Nitrogen comprises 78% by volume of the atmosphere—Oxygen which is the most abundant element on earth forms 46.6% by mass of earth's crust. Fluorine is present in insoluble fluorides. Seawater contains bromides, chlorides, and iodides of potassium, calcium, magnesium, and sodium. It is mainly sodium chloride solution.
