In the following table, six elements A, B, C, D, E and F (here letters are not the usual symbols of the elements) of the modern periodic table with their atomic numbers are given.

Which of these is a halogen ?

Text Solution

Verified by Experts

F is a halogen (chlorine) because its atomic number is 17 and electronic configuration is (2, 8, 7).
