Diatomic Molecules

Postby Sean Sugai 4E » Mon Nov 11, 2019 12:45 am

Why are all diatomic molecules composed of two different elements at least slightly polar?

because two different elements will have slightly different electronegativities

Unless they are diatomic molecules or molecules of the same atom, a molecule will never be nonpolar because of differing electronegativities.

When calculating the molar mass of 2 moles , I calculated the 14.0067 x 4 because I thought it was equivalent to 4 nitrogen atoms. Can someone explain why I'm wrong please? I know now that the molar mass should have been just 14.0067 x 2.

Sorry I read my work incorrectly, I don't need an answer

Because of their differing electronegativities, the atoms will never be nonpolar because they have differnet charges.

Unless they are the same element, all diatomic molecules are somewhat polar because every element has at least a slight difference in electronegativity that causes one atom to pull on the shared electrons more than the other.
