The atomic weight of the halogen can never have the value
Options:
Answer:
B
Solution:
Atomic weight = equivalent weight × valency (an integer). With E = 127 or 63.5, possible values include 63.5, 127, 190.5, 254; 31.75 would require valency 1/2 or 1/4, which is impossible. Hence 31.75, matching (b).
