Per NCERT Table 3.6(b), the atomic radius of HALOGENS DOWN Group 17 follows what trend?
AIncreases steadily: F 64 < Cl 99 < Br 114 < I 133 < At 140 pm
BDecreases: F > Cl > Br > I
CDoubles at each step
DStays constant
Answer & Solution
Correct answer: A. Increases steadily: F 64 < Cl 99 < Br 114 < I 133 < At 140 pm
Per NCERT Table 3.6(b), F 64 → Cl 99 → Br 114 → I 133 → At 140 pm. Increases down the group.
