The following Topics and Sub-Topics are covered in this chapter and are available on MSVgo:
It is paramount in chemistry to study elements and their atomic composition. P-Block Elements are those elements that belong to group 13 to 18 of a periodic table. The elements such as boron, carbon, nitrogen, oxygen form the part of P-Block Elements. It is called so because their valence electrons are present in the p-orbital. They are mainly found on the right side of a periodic table. It can be primarily described, in terms of column number or element type.
Characteristics of P-Block Elements can be explained in the following ways:-
Properties of P-Block Metals
Properties of P-Block Metalloids
Properties of P-Block Non-Metals
All the elements of group 13 of the periodic table are called the boron family. Boron tends to behave differently as compare to other elements in group 13 because of the following reasons:-
Trends in Properties of the Boron Family
Anomalous Properties of the Boron Family
In a periodic table, the group 14 elements are called the carbon family. They are the second group in the P-block of the periodic table. The members of this family are carbon, silicon, germanium, tin, lead, and flerovium. They generally have an electronic configuration of ns2np2. In the outermost p orbitals, these elements have 2 electrons.
Anomalous Behavior of Carbon Family
C & Si – Non-metals
Ge – Metalloid
Sn & Pb – Soft metals
Carbon due to their ability to catenate tends to form hydrides. Some of the hydrides of carbons are:- Alkanes, Alkenes, Alkynes, Aromatic compounds. It is to be noted that carbons do not form dihalides. Oxides type M0 and M02 are formed by the group 14 elements.
Chalcogens are called the oxygen group. All the elements found in group 16 of the periodic table are part of the oxygen family. The chemical symbol of oxygen is O. The oxygen family consists of oxygen, sulfur, selenium, tellurium, and polonium. They are in both free and combined states. Oxygen is an element that is known to all as it plays a very cardinal role in sustaining life on earth. It differs from the rest of the elements, because of the following reasons:-
General Properties of the Oxygen Family
How can the Chalcogens be Isolated?
P-Block Elements are very significant for class 12 exams. While grasping the P-block elements, first try to understand the core concept behind them with an explanatory video on the MSVgo app. The MSVgo philosophy is to enable a core understanding of any concept. The video library of the MSVgo app explains concepts with examples or explanatory visualizations or animations.
