If covalently bonded atoms have different electronegativities the distribution of electron density will be more towards the more electronegative atom which will acquire a slight negative charge.
Electron density distribution refers to how the electrons are spread out in space around the atoms in a bond or molecule.The electron-density distribution is the three-dimensional real-space arrangement of the electrons in the material. Because electrons are quantum mechanically delocalised, each electron occupies a 'fuzzy' region of space called an electron cloud.
