CBSE Class 11 Chemistry Chapter 10 - The s-Block Elements

Brief Information: This chapter discusses the elements present in group 1 and 2. It discusses the electronic configuration along with their occurrence. Every first element in the group shows some anomalous behavior which is also discussed in this chapter. There are diagonal relationships like atomic radii, variation in terms of properties in ionization enthalpy, ionic radii, etc is also discussed. How some of the important compounds like sodium chloride, sodium carbonate, sodium hydrogen carbonate, and sodium hydroxide are prepared is also discussed in this chapter.

Topics Covered

• Group 1 and Group 2 Elements -General introduction, electronic configuration, occurrence, anomalous properties of the first element of each group, diagonal relationship,
• Trends in the variation of properties (such as ionization enthalpy, atomic and ionic radii)
• Trends in chemical reactivity with oxygen, water, hydrogen and halogens, uses.
