MCQ
Diagonal relationship is due to:
- Aidentical ionization potential
- Bidentical electron negativity
- ✓identical sizes of ions
- Dsame valence shell configuration
✓
Answer
Correct option: C.
identical sizes of ions
The diagonal relationship is due to identical sizes of ions.
On moving rightward a period of the periodic table, the size of the atoms decreases, and on moving down a group the size of the atoms increases. Similarly, on moving rightward a period, the elements become more electronegative, whereas on moving down the group the element becomes more positive. These two factors work in opposite direction. Hence the elements that are present diagonally to each other have similar properties like atomic size, electronegativity, density, chemical properties of compounds.
