Question

Among the following which is an incorrect statement?

• A. Existence of hydrated unipositive ion of hydrogen resembles as alkali metals
• B. High ionization energy of hydrogen is 1312 KJ/mole resembles as halogens
• C. Small size of hydrogen atom and moderate electronegativity value of Hydrogen resembles as alkali metals
• D. Hydrogen has great tendency to form covalent bond like halogens

Answer 1

The correct option is C

Small size of hydrogen atom and moderate electronegativity value of Hydrogen resembles as alkali metals

All alkali metals and Hydrogen have one electron in their valence shell and has the same valency. So, they have a moderate electronegativity and a smaller size because they have only one electron missing in the valence shell.
