All the halogens are _diatomic molecules.
Correct answer: B. non polar
- A. polar
- B. non polar
- C. reactive
- D. non reactive
Explanation
All of the halogens exist as diatomic molecules. This means that the elements are made up of pairs of atoms that are chemically joined together (for example, fluorine exists as F2, chlorine as Cl 2, bromine as Br2 and iodine as I 2). Here, the diference is zero, the bond between the two atoms is non-polar covalent bond and hence molecule formed is non-polar.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
