Question

What is the main reason of diagonal relationship between lithium and magnesium?

• A. Electronegativity remains constant the same on moving parallel.
• B. 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 1

The correct option is C Electronegativity remains constant the same on moving diagonally.

The diagonally opposite elements possess almost similar electronegativities and there fore almost similar electropositive character.
