A chlorine atom, found in the periodic table's halogen group, has 17 protons and 17 electrons, making it electrically neutral. It often participates in reactions by gaining an electron to achieve a stable electronic arrangement. The chloride ion, on the other hand, results from this gain of ...
In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and tin has 50 protons and 50 electrons. The number of neutrons is very roughly the same as the number of protons, ...

when the temperature of everything was still insanely hot, at about 10 billion degrees Fahrenheit (5.5 billion Celsius),according to NASA. The cosmos now contained a vast array of fundamental particles such as neutrons, electrons and protons — the raw materials that would become the building blo...
The Large Hadron Collider is mainly a machine for smashing protons into each other. But what's a proton? First and foremost, it's a mess. A total mess. As ugly and chaotic as a hydrogen atom is elegant and simple. Ok, then, what's a hydrogen atom? It
