Which of the following explanations justifies for not placing hydrogen in either the group of alkali metals or halogens?
A
The ionization energy of hydrogen is too high for group of alkali metals and too low for halogen group.
B
Hydrogen atom does not contain any neutron.
C
Hydrogen is much lighter than alkali metals or halogens.
D
Hydrogen can form compounds with almost all other elements.
Answer
The ionization energy of hydrogen is too high for group of alkali metals and too low for halogen group.
Explanation
Solution
lonisation energy of hydrogen is (1312 kJ mol–1) which is too high than that of alkali metals and low than that of halogens.
