The electron distribution around an atom or molecule undergoes fluctuations in time. These fluctuations create instantaneous electric fields which are felt by other nearby atoms and molecules, which in turn adjust the spatial distribution of their own electrons. The net effect is that the fluctuations in electron positions in one atom induce a corresponding redistribution of electrons in other atoms, such that the electron motions become correlated. While the detailed t… Webb17 jan. 2024 · When you think of electrons around an atom, you probably picture tiny moving dots, spaced equally around the atomic nucleus. However, ...

Intermolecular forces (IMFs) are the attractive or repulsive forces between entire molecules due to differences in charge. Many students confuse IMFs with intramolecular forces, which were the center of the last unit. WebbDispersion forces that develop between atoms in different molecules can attract the two molecules to each other. The forces are relatively weak, however, and become significant only when the molecules are very close. Larger and heavier atoms and molecules exhibit stronger dispersion forces than do smaller and lighter atoms and molecules.
