Thus,statement $A$ is correct.$2$. Electronegativity is defined as the tendency of an atom in a chemical bond to attract the shared pair of electrons towards itself. It is a property of bonded atoms. Thus,statement $B$ is correct.$3$. $Al_2O_3$ and $BeO$ are well-known amphoteric oxides,meaning they react with both acids and bases. Thus,statement $C$ is correct.$4$. Since all statements $A$,$B$,and $C$ are correct,the statement 'None of these are incorrect' is the correct choice.
