Question

Compare and contrast the physical properties of group IA and IIA metals​

Answer 1

Answer:

1-Group IA elements are called as alkali metals while group IIA elements are called as alkaline earth metals.

2-The elements of IIA group have much higher boiling point as compared to those group IA.

3- Tha alkali metals and softer and more lightweight whereas alkaline earth metal much harder and danser.
