EEJ MAIN Chemistry QUESTION #7158
Question 1
Which element among the following has an electronegativity value most similar to Aluminium ($Al$)?
  • Carbon
  • Beryllium✔️
  • Boron
  • Lithium
Correct Answer Explanation
Due to the diagonal relationship in the periodic table, elements positioned diagonally to each other often show similar properties. Beryllium ($Be$) in Group 2 and Aluminium ($Al$) in Group 13 have similar electronegativity, ionic radii, and both form amphoteric oxides.
