NCERT Solutions for Class 11 Chemistry Chapter 10 The s-Block Elements

In this chapter, we study the s-block elements of the periodic table. The s-block elements of the periodic table are those elements in which the last electron enters the outermost s-subshell (or s-orbital). Two electrons are the maximum capacity of ns energy subshell. In this chapter, there are 32 questions in the exercise. The NCERT Solutions for Class 11 Chemistry Chapter 10 The s-Block Elements are designed and solved by our chemistry experts. These are the detailed explanation of NCERT textbook questions. These NCERT solutions help students in their preparation of class 11 final examination as well as in the various competitive exams like JEE, NEET, BITSAT etc.

In s-block, there is a total of two groups (1&2). In NCERT Class 11 Chemistry Chapter 10 The s-Block Elements we will discuss important concepts of s-block elements like properties of group 1 and group 2 elements, their electronic configuration, their occurrence, general characteristics of the compounds of alkali metals and alkaline earth metal, anomalous behaviour of lithium and beryllium, important compounds of sodium and calcium and at the end we will discuss the biological importance of sodium, potassium, magnesium and calcium.

We already discussed that s-block elements are divided into two groups. The elements of Group 1 are lithium(Li), sodium(Na), potassium(K), rubidium(Rb), caesium(Cs) and francium(Fr). They are collectively known as the alkali metals. The elements of Group 2 beryllium(Be), Magnesium(Mg), Calcium(Ca), Strontium(Sr), Barium(Ba) and Radium(Ra). They are collectively known as alkaline earth metals. In NCERT Class 11 Chemistry Chapter 10 The s-Block Elements, we will also discuss some important trends like atomic radius, diagonal relationship etc.

Some Important points of Class 11 Chemistry Chapter 10 The s-Block Elements

1. General electronic configuration of Group 1 elements is ns^1.

2. General electronic configuration of Group 2 elements is ns^2.

3. Generally, densities of alkali metals increase down the group from Li to Cs except for density of K < Na.

4. Alkali metals have low boiling and melting point and these decreases down the group.
