Question

Why Li and Be formed covalent compounds explain it​

Answer 1

$\huge {\underline {\purple {Answer}}}$

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 bonds.

Answer 2

Answer:

Because its atomic radius is very smaller than other elements in s - block. By its smaller radius the attraction between electrons and nucleus are more (nuclear attraction). So its covalent characters is more that's why these 2 elements form covalent bonds.
