CBSE Class 11-science - Anomalous Behaviour Videos
The s-Block Elements
This video explains the diagonal relationship between lithium and magnesium, diagonal relationship between beryllium and aluminium, and variation in the properties of Group 1 and Group 2 elements.
- Name the elements pair of s-block which show diagonal relationship.
- What are the features of lithium which separates it from other elements of Group 1?
- Why does lithium show anomalous behavior?
- State the common characteristic features of Li and Mg.
- Why does beryllium show anomalous behavior?
- What are the features which separates beryllium from magnesium and other metals of Group 2?
- Discuss any four properties which show the anomalous behavior of Be and its similarity with Al.
-
- The salts of alkali metals are the most ionic salts known. Although lithium is an alkali yet its compounds, particularly halides, are slightly covalent in nature.
- How is sodium different from potassium?
