Circling the nucleus is actually a cloud of electrons, which happen to be negatively billed. Like opposite ends of a magnet that draw in each other, the negative electrons are attracted to a constructive pressure, which binds them into the nucleus. The nucleus is little and dense in comparison While using the electrons, which are the lightest charged particles in nature. The electrons circle the nucleus in orbital paths known as shells, Every single of which holds only a particular amount of electrons.
Should the locked entry is just not certain to a single cache line things get extra intricate.
