APA TEGESÉ HEXAVALENT ING BASA INGGRIS?

Valence (kimia)

Valence (chemistry)

Ing babagan kimia, valensi unsur kasebut minangka langkah nggabungake kekuwatane karo atom-atom liya nalika mbentuk senyawa kimia utawa molekul. Konsep valensi dikembangake ing separo pungkasan abad ka-19 lan sukses njelasake struktur molekul saka senyawa organik. Penyebab saka panyebab-panyebab valensi sing nyebabake tumuju teori-teori modern saka ikatan kimia, kayata struktur Lewis, teori ikatan valensi, orbital molekul, teori hidrofobion pasangan elektron valensi, lan kabeh metode canggih kimia kuantum. Daya gabungan utawa afinitas saka sawijining unsur atom ditemtokake kanthi jumlah atom hidrogen sing digabungake. Ing karbon metana duweni valensi 4, ing nitrogen amonia ana valensi 3, ing oksigen banyu duwe valensi loro, lan klorida hidrogen klorida duweni valensi 1. Klorin, sing nduweni valensi siji, bisa diganti kanggo hidrogen, supaya fosfor nduweni valensi 5 ing fosfor pentachloride, PCl5. Valensi diagram saka senyawa minangka panyambungan unsur, garis antarane rong unsur, kadhangkala disebut ikatan, diwakili valensi sing jenuh kanggo saben unsur.

In chemistry the valence of an element is a measure of its combining power with other atoms when it forms chemical compounds or molecules. The concept of valence was developed in the last half of the 19th century and was successful in explaining the molecular structure of many organic compounds. The quest for the underlying causes of valence lead to the modern theories of chemical bonding, including Lewis structures, valence bond theory, molecular orbitals, valence shell electron pair repulsion theory and all the advanced methods of quantum chemistry. The combining power or affinity of an atom of an element was determined by the number of hydrogen atoms that it combined with. In methane carbon has a valence of 4, in ammonia nitrogen has a valence of 3, in water oxygen has a valence of two, and in hydrogen chloride chlorine has a valence of 1. Chlorine, as it has valence of one, can be substituted for hydrogen, so phosphorus has a valence of 5 in phosphorus pentachloride, PCl5. Valence diagrams of a compound represent the connectivity of the elements, lines between two elements, sometimes called bonds, represented a saturated valency for each element.
