Question

similarities between hydrogen and alkali metal​

Answer 1

Explanation:

Similar to alkali metals, hydrogen has 1 electron in its outermost shell and can form compounds with non-metals (such as HCl, etc.). However, it has non-metallic character, is a gas (while alkali metals are solid) and cannot lose its valence electron.

Answer 2

Answer: Hydrogen and alkali metals, both have 1 electron in their valence shell. Due to the metallic nature of alkali metals they are electropositive in nature. Hydrogen has dual nature. It shows both metallic and non- metallic nature. Hence, it is electronegative but electropositive also.

Therefore, alkali metals and hydrogen are similar.
