Question

The diagonal relationship between Beryllium ($Be$) and Aluminium ($Al$) is heavily pronounced in their chemistry, such as the formation of amphoteric oxides. This chemical similarity is primarily attributed to their almost identical:

Prashant Kotian · Accepted Answer

Correct answer: C. Elements located diagonally across periods 2 and 3 often share similar properties because the increase in electronegativity and polarizing power (charge/size ratio) across a period is effectively cancelled out by the decrease down a group. Thus, and have nearly identical ionic potentials and electronegativities ().
