Tennessine, Ts, is an unstable man-made element. It lies below astatine, At, in Group 17. The chemistry of Ts and its compounds has only been predicted. Suggest an equation for the reaction of NaTs and $\text{Br}_2$. Assume that Ts follows the same patterns as the other elements in Group 17. Explain your answer.
(b(ii))[2]
Complete Table 2.2 with the predicted melting point of tennessine and the lattice structure of solid chlorine, bromine and tennessine. Assume that Ts has properties typical of metals like copper.
