JEE Advanced: Alkali Metals

Group 1 Reactions & Trends for chemca.in

Diagonal Relationship

Li & Mg: Similar ionic sizes (Li+ = 76pm, Mg2+ = 72pm) lead to similar properties: both form nitrides, decompose carbonates easily, and have covalent halides.

Solubility Trends

Carbonates: Solubility increases down the group. Li2CO3 is the least soluble.

Halides: LiF is low solubility (high lattice energy); CsI is low solubility (low hydration energy).
