Thallium is found in significant amounts. One unit at the Experiment Station developed explosives and fuses. Thallium azide, thallium nitride, and thallium fulminate are shock sensitive explosives and emit poisonous fumes. It would have been an ideal subject of experimentation. Thallium as high as 58.52 ppm was found. The oral LDjg for rats is 16 mg/kg, and the LDjo for children is 8 mg/kg. LDjg is the lethal dose at which 50 percent of the population dies. 

Only thallium of the Group III elements is affected by air at room temperature and thalliumflll) oxide is slowly formed. All the elements, however, burn in air when strongly heated and, with the exception of gallium, form the oxide M2O3 gallium forms a mixed oxide of composition GaO. In addition to oxide formation, boron and aluminium react at high temperature with the nitrogen in the air to form nitrides (BN and AIN). 

The binary compounds of the Group 13 metals with the elements of Group 15 (N, P, As, Sb, Bi) are stmcturally less diverse than the chalcogenides just considered but they have achieved considerable technological application as III-V semiconductors isoelectronic with Si and Ge (cf. BN isoelectronic with C, p. 207). Their stmctures are summarized in Table 7.10 all adopt the cubic ZnS stmcture except the nitrides of Al, Ga and In which are probably more ionic (less covalent or metallic) than the others. Thallium does not form simple compounds... 

M X the explosive black nitride T1 3N is known, and the azides T1 N3 and T1 [T1 (N3)4] the phosphides TI3P, TIP3 and TIP5 have been reported but are not well characterized. With As, Sb and Bi thallium forms alloys and intermetallic compounds TI3X, Tl7Bi2 and TlBi2.

Thallium(I) nitride is a highly explosive black solid,1 but the yellow azide T1N3 is more stable the physical properties suggest that there is some covalent T1—N bonding in the solid state. The mechanism of the decomposition has been reviewed.287...

Heavy metal compounds tend to be toxic and require careful handling some of those are compounds of lead, thallium, mercury, and barium. Provide the formulas of these heavy metal bromides, sulfides, nitrides, and carbonates. The more common oxidation numbers of the metals having more than one are Pb2+, T1+, Hg2+.
