Temporary charges that come and go

Detailed explanation-1: -Different atoms have different electronegativities based on how many valence electrons they already have. Atoms of different electronegativities attract electrons unequally. This causes the unequal sharing of electrons, which causes polarity in bonds.
Detailed explanation-2: -When in a molecule the valence electrons are shared between the atoms, a covalent bond is formed. Complete answer: When the electrons are unevenly distributed or are unequally shared, the bond formed is known as a polar covalent bond.
Detailed explanation-3: -Answer and Explanation: The type of bond that has unequal sharing of bonded electrons is a polar covalent bond. In a polar covalent bond one atom is more electronegative than the other. It pulls the electrons closer towards its nucleus and gains a partial negative charge.
