Anand Classes brings you a detailed explanation of the Periodic Variation of Electronegativity for Class 11, NEET, and JEE aspirants. Electronegativity is a fundamental concept in chemistry that helps us understand how atoms attract shared electrons in a covalent bond. In this study material, we explain how electronegativity changes across a period and down a group in the periodic table, along with its relation to atomic size, effective nuclear charge, and ionization enthalpy. This topic is extremely important for competitive exams as well as CBSE board preparation. Click the print button to download study material and notes.

Anand Classes provides comprehensive study material on Electronegativity and its relation to Metallic and Non-Metallic Character for Class 11, NEET, and JEE preparation. Understanding electronegativity trends across the periodic table is essential to predict the chemical behavior of elements, bond formation, and the distinction between metals, non-metals, and metalloids. This concept also helps students in mastering important topics like periodic properties, bond polarity, and the classification of elements.

Anand Classes provides a detailed NCERT Intext 3.2 solution for Class 11 Chemistry: How would you justify the presence of 18 elements in the 5th period of the Periodic Table? The explanation is based on the electronic configuration, filling of orbitals, and periodic trends that determine why exactly 18 elements are present in the 5th period. This makes it easier for JEE, NEET, and CBSE students to understand the concept clearly with proper reasoning. Click the print button to download study material and notes.

Anand Classes provides the detailed NCERT Intext 3.3 solution for Class 11 Chemistry: The elements Z = 117 and 120 have not yet been discovered. In which family/group would you place these elements and also give the electronic configuration in each case? The solution explains how Z = 117 belongs to the halogen family (Group 17) with configuration [Rn] 5f¹⁴ 6d¹⁰ 7s² 7p⁵, and Z = 120 belongs to the alkaline earth metals (Group 2) with configuration [Uuo] 8s². This explanation is important for JEE, NEET, and CBSE students to understand periodic table predictions. Click the print button to download study material and notes.

Anand Classes provides the NCERT Intext 3.4 solution for Class 11 Chemistry: Considering the atomic number and position in the periodic table, arrange the following elements in the increasing order of metallic character: Si, Be, Mg, Na, P. The solution is explained with periodic trends, showing how metallic character increases down a group and decreases across a period. Hence, the increasing order of metallic character is P < Si < Be < Mg < Na. This clear explanation is highly useful for JEE, NEET, and CBSE Class 11 students.

Anand Classes provides the NCERT Intext 3.5 solution for Class 11 Chemistry: Which of the following species will have the largest and the smallest size: Mg, Mg²⁺, Al, Al³⁺? The solution is explained using periodic trends, effect of cation formation, and the concept of isoelectronic species. It is concluded that the largest species is Mg, while the smallest species is Al³⁺. This step-by-step explanation is very useful for JEE, NEET, and CBSE Class 11 Chemistry students.
