Polarity is.. 1) When electrons are not shared between atoms in a compound 2) When electrons are shared unevenly among the atoms in a compound 3) when protons are shared evenly among the atoms in a compound 4) When electrons are shared evenly among the atoms in a compound

The correct option is 2) When electrons are shared unevenly among the atoms in a compound

Explanation:

Polarity is the property of a molecule in which the atoms share electrons in an uneven way. This is due to differences in the electronegativity of the atoms. The atom with a higher electronegativity will attract with a higher strength the electrons. Thus, a separation of charges is produced: the atom with more electrons has a more negative charge while the atom with fewer electrons has a more positive charge. This charge separation generates a dipolar moment, which means: polarity.

the answer is symmetrical : )
