MOLECULAR POLARITYFIELD NOTE 128 / 175
Is I2 polar or nonpolar?
I2 is a nonpolar molecule because both iodine atoms are identical and share electrons equally, producing no net dipole.

Why I2 is nonpolar
Iodine exists as a diatomic molecule with two identical iodine atoms bonded by a single covalent bond.
What to notice
A large iodine atom does not create a dipole by itself. Two identical iodine atoms share the I–I bond equally.
Common questions about I2
- 01
What does the Lewis structure of I2 show?
The two I atoms share one single bond, and each iodine has three lone pairs.
- 02
What is the molecular geometry of I2?
I2 is a two-atom molecule, so its geometry is linear. A bond angle needs three atoms and is not defined here.
- 03
What is the molar mass of I2?
I2 has an approximate molar mass of 253.80 g/mol, calculated from its formula using abridged standard atomic weights. Natural isotope variation can change the last digits.
