Preface It gives me great pleasure to present to you the second edition of All About Chemistry ICSE Question Bank – a collection of question papers. The primary aim of this question bank is to provide the students with a clear idea about the type and pattern of questions that normally come in ICSE exams. These questions are designed in total conformity with the reduced syllabus of ICSE 2022(Bifurcated Syllabus). I hope this book would cater to the requirements of both students and teachers. This book consists of To the point study material on each topic.  Solved ICSE question papers from 2015 to 2021  Unsolved 11 Progress test (Chapter wise)  Unsolved 20 practice sets  900 questions with answer key  Unsolved additional 100 harder questions  Chapterwise MCQ tests  Semester wise MCQ tests  5 Full syllabus MCQ tests Finally, I express my sincere gratitude to my publisher and seller. Special thanks to my brother Mr. Monojit Oraon, who has inspired and motivated me in this journey. Biswajit Das

Chapter 1: Periodic Properties and variations of Properties – Physical and Chemical 1.

Modern Periodic Law: The physical and chemical properties of the elements are the periodic function of their atomic number.

2.

Periodicity of properties and its cause: Repetition of the properties of elements after certain intervals is called periodicity. The basic cause of periodicity is the periodic repetition of outer electronic configuration of the elements at regular intervals of 2, 8, 8, 18, 18, and 32.

3.

Physical properties - Atomic volume, atomic size, melting point, boiling point and density.

b) Chemcal PropertiesElectronic configurations, ionization energy, electron affinity, electronegativity, metallic character, nature of oxides, oxidation state and reducing character. c)

5.

Specific heat, refractive index are not periodic properties.

Atomic size or radii: The distance between the centres of nucleus of atom to its outermost shell of electrons. Factors influencing atomic radii: a)

Number of shells: With the increase in the number of shells, atomic size increases.

b) Nuclear charge: With the increase in nuclear charges, atomic size decreases. 6.

Variation of atomic radii: a)

Across the period, atomic radius (Covalent) decreases

b) Down a group atomic radius increases. c)

This decrease and increasing order are valid till group 17. For group 18, van der Waal radius is taken into consideration, thus all of a sudden the atomic size increases from group 17 to 18.

d) In period 2, Li>Be>B>C>O>F>N e)

In period 3, Na>Mg>Al>Si>P>S>Cl

The size of the transition elements hardly changes.

g) Atomic size of anion > cation h) For isoelectronic species, ionic radii decrease with the increase in the magnitude of the nuclear charge. Al3+
