Question

When two bonded atoms have significantly different electronegativities, we say that the bond is polar because one atom will be slightly positive (the nucleus is exposed) and the other will be slightly negative (extra electron density). Which atom will be slightly negative in a polar bond? Use information in the previous problem also.

(1pts)

The less electronegative atom will be slightly negative.

The lighter atom will be slightly negative.

The heavier atom will be slightly negative.

The more electronegative atom will be slightly negative.

Answer 1

The less electronegative atom will be slightly negative ---> False, this will be positive mostly

The lighter atom will be slightly negative --> its not about mass but charge

The heavier atom will be slightly negative ---> false, not abut mass

The more electronegative atom will be slightly negative.--> correct, the eletron distribution depends mainly on the electronegativities of species

therefore

chooose

The more electronegative atom will be slightly negative.
