Hydrogen has _____________ ionization enthalpy.(a) high(b) low(c) zero

1.	Hydrogen has _____________ ionization enthalpy.(a) high(b) low(c) zero(d) noThe question was posed to me in semester exam.I'd like to ask this question from Position of Hydrogen in the Periodic Table in portion Hydrogen of Chemistry – Class 11
Answer» The correct answer is (a) high The best I can explain: Though hydrogen is PLACED in the FIRST group which is of alkali metals, it has a very high ionization ENTHALPY this is because it has a characteristic of a halogen as WELL. We can say that hydrogen is an alkali metal and a halogen at a TIME.
