MCQ
$Be$ and $Al$ show diagonal relationship hence, both have:
  • A
    Same degree of electronegativity.
  • B
    Amphoteric nature of oxides.
  • C
    Approximately same charge$/$ radius ratio.
  • ✓
    All the properties above.
✓

Answer

Correct option: D.
All the properties above.
Metal hydroxides with a highly $-$ charged central metal atom forms amphoteric. In addition to aluminum, metals such as zinc, tin, lead, and beryllium also forms amphoteric oxides.
The two elements have same electronegativity and their charge$/$ radius ratios.
