Question : Which of the following is not a donor atom?
Option 1: Phosphorus
Option 2: Antimony
Option 3: Arsenic
Option 4: Aluminium
Correct Answer: Aluminium
Solution : The correct option is Aluminium .
Aluminium does not serve as a donor atom. It is less likely to act as a donor atom because it typically forms bonds by sharing electrons in covalent bonds, but it does not usually donate its electrons to form coordinate bonds in the same way that elements with lone pairs, such as phosphorus, arsenic, and antimony, do.
