CHXI11:THE P-BLOCK ELEMENTS

316501 The correct order of density of group IIIA elements as follows

1 B \(>\mathrm{Al}>\mathrm{Ga}>\) In \(>\mathrm{Tl}\)
2 B \( < \mathrm{Al} < \mathrm{Ga} < \) In \( < \mathrm{Tl}\)
3 In \( < \mathrm{Tl} < \mathrm{B} < \mathrm{Al} < \mathrm{Ga}\)
4 \(\ln =\mathrm{Ga}=\mathrm{Al} < \mathrm{B} < \mathrm{Ga}\)
CHXI11:THE P-BLOCK ELEMENTS

316502 Which of the following statements is correct regarding group 13 elements?
(I) Density increases down the group from B to \(\mathrm{Ga}\) and then decreases upto \(\mathrm{Tl}\)
(II) Boiling point of gallium is very high (2676 \(\mathrm{K})\)
(III)Boron is a soft non-metal
