Hydrogen resembles halogens in many respects for which several factors are responsible. Among the following factors, the most important factor in this respect is
1 its tendency to lose an electron to form a cation.
2 its tendency to gain a single electron in its valence shell to attain a stable electronic configuration.
3 its low negative electron gain enthalpy value.
4 its small size.

Why does \(\mathrm{\mathrm{H}^{+}}\)ion always get associated with other atoms or molecules?
1 Ionisation enthalpy of hydrogen resembles that of alkali metals.
2 Its reactivity is similar to halogens.
3 It resembles both alkali metals and halogens.
4 Loss of an electron from hydrogen atom results in a nucleus of very small size as compared to other atoms or ions. Due to small size it cannot exist in free state.
