Question

Fluorine shows anomalous behaviour in many properties. Which of the following is one of the reasons for it?

• A. Large size of its atoms
• B. Low ionisation enthalpy
• C. Availability of d orbitals
• D. Highest electronegativity

Answer 1

Answer:

D. Highest electronegativity

• Fluorine is the first member of Group 17 (the halogens), • It is the most electronegative element in the entire periodic table (4.0 on the Pauling scale). This makes it very greedy for electrons and significantly affects its bonding characteristics.
