MCQ
What is the main reason of diagonal relationship between lithium and magnesium?
  • A
    Electronegativity remains constant the same on moving parallel.
  • Electronegativity remains constant the same on moving horizontally.
  • C
    Electronegativity remains constant the same on moving diagonally.
  • D
    Electronegativity remains constant the same on moving vertically.

Answer

Correct option: B.
Electronegativity remains constant the same on moving horizontally.
The diagonally opposite elements possess almost similar electronegativities and there fore almost similar electropositive character.
