Which of the halogen can displace other three elements?
Correct answer: A. Fluorine
- A. Fluorine
- B. Chlorine (Cl)
- C. Bromine (Br)
- D. Iodine (I)
Explanation
Fluorine's exceptional reactivity:Fluorine is the most reactive element among all halogens, and its high reactivity extends to its ability to displace other halogens from their compounds.Displacement reactions:In a displacement reaction, a more reactive element displaces a less reactive element from its compound.Here are examples of fluorine displacing other halogens:Fluorine displacing chlorine: F2 + 2NaCl → 2NaF + Cl2Fluorine displacing bromine: F2 + 2KBr → 2KF + Br2Fluorine displacing iodine: F2 + 2KI → 2KF + I2

About Transition Elements
Transition elements are identified by their partially filled d subshells in atoms or common ions. The topic covers the electronic structure of d-block elements, including the filling order of 4s and 3d orbitals, variable oxidation states and the distinction between transition elements and elements with completely filled d subshells.
