Be and Al show diagonal relationship hence both have:
Option: 1
Amphoteric nature of oxides
Option: 2
Polarising nature
Option: 3
Same degree of electronegativity
Option: 4
All the above
Answers (1)
The oxides of both Be and Al are amphoteric in nature. The polarising power of Be2+ and Al3+ ions is high. Consequently the compounds develop covalent nature. The electronegativity values of both the elements are the same.
Therefore, Option(4) is correct.
