That is, a proton and an electron will attract each other. The closer they space together, the more powerful this attraction will certainly be. Two protons (or 2 electrons) will repel every other. And also again, the closer with each other they are, the more powerful the repulsion. Currently the cell nucleus of an atom is positively charged, while electrons space negatively charged. Together a result, a cell core will tempt electrons. This electrons will swarm approximately the nucleus, and the an outcome is an atom.Now we haven"t defined everything yet. The electrical force describes how the electrons space bound come the cell core of an atom. Yet we haven"t stated anything around what stop the nucleus together. The electric force can"t account because that this, and in fact, the electrical force actually works versus holding the cell core together. Remember, the nucleus has neutrons and also protons. The neutrons are electrically neutral, and so the electric force won"t hold them in. Furthermore, the protons space all positively charged, and also so they every repel each other. So if the electric force to be the only force involved, girlfriend couldn"t develop a nucleus. Friend could shot to push all those protons and neutrons together, yet as soon as you let go, the protons would all shoot far from each other, and the neutrons would certainly drift apart as well. There has to be some other pressure that holds protons and also neutrons together.Of course, because the electric force is constantly make the efforts to journey the protons apart, the pressure that holds them all in need to be more powerful than the electric force. And also keep in mind, the electric force gets stronger as fee particles gain closer together, and also the proton in a cell core are very close together. As a result, the force that holds protons and also neutrons together should be really strong. Well, in a brilliant stroke the imagination, physicists have named this pressure "the strong force." The strong force is a force which attracts protons to protons, neutrons to neutrons, and protons and neutrons to each other. The force has a very short range, and this is the reason the cell core of an atom turns out to it is in so small. In addition, the strong force is also responsible because that binding the quarks and also gluons into protons and also neutrons.

Therefore the nucleus of one atom is held together by the solid force, while the electrons are hosted in the atom by the electric force. If you"re an ext interested in these forces, you could want to try Dave"s Microcosmos.Next pagePrevious pageThe atom
