Introduction to Group 13 Elements
CHXI11:THE P-BLOCK ELEMENTS

316485 Thallium shows +1 oxidation state in its stable compounds because

1 Of its high reactivity
2 Of inert pair effect
3 Of its amphoteric nature
4 It is a transition metal
CHXI11:THE P-BLOCK ELEMENTS

316486 Read the Statement - A and Statement - B carefully to mark the correct options given below
Statement A :
In group 13, the stability +1 oxidation state increases down the group.
Statement B :
The atomic size of gallium is greater than that of aluminium.

1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.

316487 Aluminium is usually found in +3 oxidation state.In contrast, thallium exists in +1 and +3 oxidation states. This is due to

1 Lattice effect
2 Lanthanoid contraction
3 Inert pair effect
4 Diagonal relationship.
