MCQ
In which of the following respect, electronic configuration of hydrogen has resemblance to alkali metals and halogens respectively?
  • ✓
    It lose one electron to form unipositive ion and gain one electron to form uninegative ion.
  • B
    It gain one electron to form uninegative ion and lose one electron to form unipositive ion.
  • C
    It has the ability only to gain one electron.
  • D
    None of the above.
✓

Answer

Correct option: A.
It lose one electron to form unipositive ion and gain one electron to form uninegative ion.
Hydrogen has resemblance to the alkali metals, which lose one electron to form unipositive ions, as well as with halogens, which gain one electron to form uninegative ion.
