Q. Show the Chemical Properties of Group 13?
Elements of Group 13 are comparatively less reactive than the alkali and alkaline earth metals of Groups 1 and 2 However, the +activity of the elements increases on descending the group. The crystalline form of boron is black. Very hard and inert it reacts with other elements only at L.gh temperatures. The more common amorphous form is brown and more reactive than the black crystalline form. Aluminium is a light and hard white metal. It reacts with atmospheric oxygen with the formation of a protective layer of aluminium oxide which prevents further attack. Amalgamation with mercury removes the oxide coating and rapid reactions occur with oxygen, water or dilute acids. Gallium, indium and thallium are relatively soft and more reactive than boron and aluminium.
All the elements except thallium when heated with halogens, oxygen or chalcogens form halides (EX3), oxides (E203), chalcogenides (E2S3, etc.). Thallium on the other hand forms TIX, T120, T12S, etc.
