You are watching: What happens when sodium undergoes a chemical reaction with chlorine
Neutral atoms and their linked ions have incredibly various physical and muzic-ivan.infoical properties. Sodium atoms develop sodium steel, a soft, silvery-white steel that burns intensely in air and also reacts explosively through water. Chlorine atoms create chlorine gas, Cl2, a yellow-green gas that is incredibly corrosive to the majority of metals and very poisonous to pets and also plants. The vigorous reaction in between the facets sodium and also chlorine develops the white, crystalline compound sodium chloride, widespread table salt, which includes sodium cations and chloride anions (Figure (PageIndex1)). The compound written of these ions exhibits properties entirely various from the properties of the aspects sodium and chlorine. Chlorine is poisonous, yet sodium chloride is crucial to life; sodium atoms react intensely through water, yet sodium chloride ssuggest dissolves in water.
When two atoms strategy each other, they have actually the potential to bond (or connect). If a steel and also a nonsteel communicate, then an ionic bond will certainly result. These kinds of bonds involve the steel donating it(s) valence electron(s) to a nonmetal. As the digital carry occurs, both atoms will accomplish more steady confirmations. The end outcome will be a less reenergetic compound. These kind of species are written of both cations and also anions. In addition, they are crystalline and also solid in nature (Figure (PageIndex2)). A few examples of real-world ionic compounds would certainly be NaCl (table salt) and also NaF (energetic ingredient in toothpaste).The formula for table salt is NaCl. It is the outcome of Na+ ions and Cl- ions bonding together (Figure (PageIndex3)). If sodium steel and also chlorine gas mix under the best problems, they will certainly create salt. The sodium loses an electron, and also the chlorine gains that electron. This reaction is highly favorable because of the electrostatic attraction in between the particles. In the process, a good amount of light and heat is released. The resulting salt is mostly unreactive — it is stable. It will certainly not undergo any explosive reactions, unfavor the sodium and also chlorine that it is made of.
