Which of the following explanations justifies for not placing hydrogen in either the group of alkali metals or halogens?
1 The ionisation enthalpy of hydrogen is too high for group of alkali metals and too low for halogen group
2 Hydrogen atom does not contain any neutron
3 Hydrogen is much lighter than alkali metals or halogens
4 Hydrogen can form compounds with almost all other elements.
Explanation:
Hydrogen has ionisation enthalpy value which is too high as compared to alkali metals and too low as compared to halogens and thus cannot be placed in any of these two groups.

Statement A : Hydrogen is placed separately in the periodic table. Statement B : Hydrogen is extremely small in size as compared to the normal atomic and ionic sizes of 50 to \({\text{200 }}\) \({\text{pm}}\)
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Hydrogen is extremely small in size as compared to normal atomic and ionic sizes of 50 to \({\text{200}}\) \({\text{pm}}\). As a consequence, \(\mathrm{H}^{+}\)does not exist freely and is always associated with other atoms or molecules. Thus, it is unique in behaviour and is therefore, best placed separately in the periodic table.

Hydrogen accepts an electron to form inert gas configuration. In this it resembles

Statement A : Hydrogen combines with other elements by losing, gaining or sharing of electrons. Statement B : Hydrogen forms electrovalent and covalent bonds with other elements.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
