I know atoms are hosted together by Ionic and also Covalent bonds and i recognize the ionically bonded atom are organized together by electrostatic forces. What around covalent bonds?

How space molecules of external inspection atoms hosted together?Are ionic compounds simply aggregates the oppositely charged ions and hence don"t have any type of definitive "molecules". What about molecules the covalently external inspection atoms?




You are watching: What holds the atoms in a molecule together?

In non-nuclear smashville247.net, everything is electrostatic interactions. This is why you have the right to learn and predict so much just by "following the electrons"

So the brief answer to your an initial question is: "Molecular orbitals host atoms together in covalent bonds, and those are a result of electrostatic interactions and also the quantum nature of electrons."

In this picture, red way "more electrons" and also blue way "less electrons." Water can type hydrogen bonds, which are very strong electrostatic interactions. Part atoms and also molecules have actually an almost uniform charge density on the surface. We call these "non-polar" molecule - noble gases are good examples. However, also noble gases have actually what is dubbed an induced dipole due to statistically correlated fluctuations in electron thickness when the atoms are near each other. Together a result, also noble gases can be cooled come the point where they end up being liquid - the very, an extremely weak electrostatic interactions will host them together at low temperature, when they are not moving really fast. These pressures are called London Dispersion forces - after the male who an initial described them. London dispersion pressures are important, since they are discovered in all molecules - polar or not. In fact, this is what makes most plastics solid.

Polyethylene, because that example, is make of really long chains of essentially non-polar molecule (from wikipedia):

Each chain is attracted to the others with weak London dispersion forces, however, since each chain has actually tens of hundreds of atoms, those tiny pressures quickly add up come make large forces holding the polymer together. This is why polyethylene is solid in ~ room temperature, and can be used to do things favor shopping bags!
