Solution
Hydrogen was not given fixed position because:
The electronic configuration of hydrogen is 1s1alkali metals also have ns1 configuration of their outermost shell. Thus hydrogen resembles them in electronic configuration, but
hydrogen has similar chemical properties to that of halogens. This can be explained as halogens need 1 electron to have fully filled orbitals as do hydrogen.
