Question

Why does lithum forms covalent bon unlike other alkali metals for ionic bond

Answer 1

The atomic and ionic radii of Li are very small. Therefore, the nuclear attraction is strong compared to the rest of the alkali metals, which leads to a greater polarising power in Li ion, and the formation of covalent bond..... Hope it helps uh..
