Question

Compare hydrogen and halogens on the basis of physical state, ion formation ,valency and reaction with oxygen

Answer 1

if we compare hydrogen and halogens on the basis of physical state then both are gas in the basis of information both form negative formation of iron and in the basis of valency both have valency 1 and reaction with oxygen to form water vapour and the reaction is not very harmful

Answer 2

Answer:

COMPARING HYDROGEN AND HALOGEN

Explanation:

Physical state-Hydrogen and halogen both exist in gaseous state.

Ion formation-Both of them form anions since they are one electron short of their nearest noble gas' electronic configuration.

Valency-Both have valency 1.
