Which of the following is not a chemical property of Group 13 elements?
They have a valence electron configuration of .
They form stable +3 oxidation states.
They exhibit amphoteric behaviour.
They readily form compounds with halogens.
Group 13 elements have a valence electron configuration of . The other options are all true statements about the chemical properties of Group 13 elements. They form stable +3 oxidation states due to their tendency to lose their valence electrons exhibit amphoteric behaviour because they can act as both acids and bases, and readily form compounds with halogens due to their electronegativity difference. Hence option 1 is the correct answer.
Option(2) They form stable +3 oxidation states due to their tendency to lose their valence electron. Hence option 2 is incorrect.
Option(3) They exhibit amphoteric behaviour because they can act as both acids and bases, Hence option 3 is incorrect.
Option(4) They readily form compounds with halogens due to their electronegativity difference. Hence option 4 is incorrect.
