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.

Considering atomic number and position in periodic table, arrange elements (Si, Be, Mg, Na, P) in increasing order of metallic character | NCERT Intext 3.4 Question Solution

Modern periodic law and modern periodic table (groups, periods, blocks) | class 11 cbse 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.
