Which of the following properties of hydrogen is similar to halogen family?
Which of the following properties of hydrogen is similar to halogen family?
Ionisation enthalpy
Formation of unipositive ion
Electronic configuration
Electron gain enthalpy
Solution
Like halogens, hydrogen exists as a diatomic gas. Like halogens, hydrogen exhibits -1 oxidation state in its compounds with metals. Like halogens, hydrogen is liberated at cathode. The ionisation energy of hydrogen is quite close to halogens.
