Question

Give reason for anomalous position of hydrogen in the periodic table ?
correct answer pls
​

Answer 1

Answer:

Hydrogen resembles both alkali metals and halogens. It can lose one electron like alkali metals and also gain one electron like halogens. ... Therefore, position assigned to hydrogen in the periodic table is considered anomalous...

Hope it helps you (≧▽≦)

Answer 2

Hydrogen's valency (1) is similar to both the 1st group and the 17th group.

There is an anomaly when it comes to the position of hydrogen in the periodic table because, it can either be placed in the 1st group or the 17th group. It shows properties of both. Hydrogen can either lose one electron like the alkali metals in the 1st group or gain one like the halogens in the 17th group.
