[26][27] Cryptands, like crown ethers and other ionophores, also have a high affinity for the sodium ion; derivatives of the alkalide Na− are obtainable[28] by the addition of cryptands to solutions of sodium in ammonia via disproportionation. [64] Sodium reacts with alcohol and gives alkoxides, and when sodium is dissolved in ammonia solution, it can be used to reduce alkynes to trans-alkenes. [42] Because of its high reactivity, it is never found as a pure element. For example, element 120 has the temporary name unbinilium. Some comets have a sodium tail,[47] which was first detected in observations of Comet Hale-Bopp in 1997. It is identical to the charge number of the nucleus.

It reacts with chlorine … [25] For example, 15-crown-5 has a high affinity for sodium because the cavity size of 15-crown-5 is 1.7–2.2 Å, which is enough to fit the sodium ion (1.9 Å). Because there is the same number of protons as electrons in an atom (uncharged atom), this number also indicates the number of electrons in an atom. [72] If a reactor needs to be shut down frequently, NaK is used; because NaK is a liquid at room temperature, the coolant does not solidify in the pipes. Rate it: (0.00 / 0 votes) opposite number Sodium-calcium alloys are by-products of the electrolytic production of sodium from a binary salt mixture of NaCl-CaCl2 and ternary mixture NaCl-CaCl2-BaCl2.

[94] Excess sodium in the soil can limit the uptake of water by decreasing the water potential, which may result in plant wilting; excess concentrations in the cytoplasm can lead to enzyme inhibition, which in turn causes necrosis and chlorosis. Switch to new thesaurus. [32], Because of its importance in human health, salt has long been an important commodity, as shown by the English word salary, which derives from salarium, the wafers of salt sometimes given to Roman soldiers along with their other wages. The insolubility of certain sodium minerals such as cryolite and feldspar arises from their polymeric anions, which in the case of feldspar is a polysilicate. - Science and Technology 1 Definition a light silvery malleable and ductile metallic element, also ALUMINIUM, ALUMIUM . ; Symbol: Z See more.

[70] The high boiling point of sodium allows the reactor to operate at ambient (normal) pressure,[70] but the drawbacks include its opacity, which hinders visual maintenance, and its explosive properties. Scientists determine the atomic mass by calculating the mean of the mass numbers for its naturally-occurring isotopes. [36] The chemical abbreviation for sodium was first published in 1814 by Jöns Jakob Berzelius in his system of atomic symbols,[37][38] and is an abbreviation of the element's New Latin name natrium, which refers to the Egyptian natron,[33] a natural mineral salt mainly consisting of hydrated sodium carbonate. [34][35] In 1809, the German physicist and chemist Ludwig Wilhelm Gilbert proposed the names Natronium for Humphry Davy's "sodium" and Kalium for Davy's "potassium".

The number of protons define the identity of an element (i.e., an element with 6 protons is a carbon atom, no matter how many neutrons may be present). Look up the English to German translation of atomic number 11 in the PONS online dictionary. [86][87]), One study found that people with or without hypertension who excreted less than 3 grams of sodium per day in their urine (and therefore were taking in less than 3 g/d) had a higher risk of death, stroke, or heart attack than those excreting 4 to 5 grams per day. [44], Sodium has also been detected in numerous Solar System environments, including Mercury's atmosphere,[45] the exosphere of the Moon,[46] and numerous other bodies.
