Sol 10:
Correct option : (c) Br
Chlorine is the second halogen, being a nonmetal in group 17 of the periodic table. Its properties are thus similar to fluorine, bromine, and iodine, and are largely intermediate between those of the first two.
Sol 11: Period 6 (including lanthanoids)
Period 6 contains 26 metals
