Due to the proximity of a wide range of elements, the p-block shows a lot of variety in properties.īoron Family (Group 13 Elements ) Boron Family (Group 13 Elements ) We uncover the metalloids along the line. Metals are to be found on the left of the line, and those on the right are non-metals. The crisscross path in the p-block isolates each of the elements that are metals from nonmetals. Sixth group: zero group or group 18 known as Inert or Noble gasses group.Īll three kinds of elements - the Metals, Non-Metals, and Metalloids, are available in the p-block. Third group: group VA known as Nitrogen group.įourth group: group VIA known as Chalcogens.įifth group: group VIIA known as Halogens. Second group: group IVA known as Carbon group. Resultantly, the periodic table numbered from 13 to 18 shows six groups of p-block elements.įirst group: group IIIA known as Boron group As we know that the quantity of p orbitals is three, the most drastic number of electrons that can be compelled in a p orbital structure is six. In the periphery shell, they have 3 to 8 electrons. The last electron enters the furthest p orbital in the p-block elements. Positions of p-Block Elements Positions of p-Block Elements in the Periodic Table On a general note, elements that have a position within group 13 (group IIIA) to group 17 (group VIIA) of the periodic table along with group 18 which is the zero group elements form the p-Block of the periodic table together. Questions can be asked from important sub topics such as general trends in physical and chemical properties of elements and compounds like Boron, Silicon, Nitrogen, Phosphorus, Sulphur, and Halogens. Therefore, 1-2 questions are sure to be asked from this chapter. The chapter on p-Block elements carries a weightage of around 6% in the Chemistry section in JEE Main. p-Block elements is one of the most important topics asked from Inorganic Chemistry. NCERT will teach you all about block chemistry and its reactions. Study in detail to be clear with the concepts of bonding and coordination chemistry.

Moreover, most of the questions come directly from NCERT. Inorganic Chemistry has equal weightage compared to Organic and Physical Chemistry, but it is relatively simple, scoring and requires less time.
