hello dear,

Explanation:

Hydrogen is placed in Group 1 element of the modern periodic table due to following reasons:

1.It shows outer electronic configuration similar to group 1 elements I.e. 1s^1

2. It readily loose its electron to form H^+ ions which resembles the electro positive character of group 1 element .

3. It slows +1 oxidation state like Alkali metals.

4. It also acts like reducing agent and form binary compound with electronegative elements , e.g. HCl, HBr

like Alkali metals of Group 1

if it helps u then ,

thank u very much dear
