Rhenium, Internal Combustion Engines and Biofuel.

185 Re 187 Re. Login to your account. Since it has the atomic number 75 it has 75 protons and when it is an atom and not ionized it will also have 75 electrons. The element rhenium (Re) exists as two stable isotopes and 18 unstable isotopes, Rhenium-185 has in its nucleus 75 protons, 110 neutrons How many significant figures should be reported for the difference between 18.6150 mL and 18.57 mL? recent questions recent answers. a.75 protons, 75 neutrons. A. Rh B. The element rhenium (RE) exists as two stable isotopes and 18 unstable isotopes. Rhenium diboride (ReB 2) Rhenium oxide (Re 2 O 7) Rhenium trichloride (ReCl 3) Rhenium trioxide (ReO 3) Interesting facts: It has the third highest melting point with tungsten and carbon being higher. Rhenium is a rare, silvery-white, lustrous, dense metal. For example, two of the most abundant isotopes are rhenium-185 and rhenium-187. The ground state electron configuration of ground state gaseous neutral rhenium is [Xe].4f 14.5d 5.6s â¦ Answer for question: Your name: Answers. To calculate the remaining number of electrons, you subtract the amount of extra charge from the atomic number. In general, an atomâs electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. Group 18 elements (helium, neon, and argon are shown) have a full outer, or valence, shell. Given the weighted average atomic mass of rhenium (186.207 amu), what are the percent abundances of rhenium - 185 and rhenium - 187 respectively? Medium = substitution is possible but there may be an economic and/or performance impact TheÂ chemical symbolÂ for Copper isÂ Cu. A. Isotopes: Rhenium has 33 isotopes whose half-lives are known, with mass numbers from 160 to 192. study As a matter of fact, it is the third highest melting point. Rhenium is a silvery-white, heavy, third-row transition metal in group 7 of the periodic table. Rhenium is a chemical element with the symbol Re and atomic number 75. How many valence electrons does Ru have? From periodic table ,we see that the atomic number of potassium is 19. Key Points. You get the neutrons by subtracting the atomic number from the atomic mass.185 is â¦ They have the same number of electrons, but different number of electrons. For example, Ca 2+ has a +2 charge so it has lost 2 electrons from the neutral state. Ru(II) Ru(III) and Ru(IV) are the most common. Ethanol in alcoholic drinks, such as beer and wine, is produced from the sugars in vegetable matter such as fruits.

The RSC makes no representations whatsoever about the suitability of the information contained in the documents and related graphics published on this Site for any purpose. B. Step-1: First, find the atomic number of potassium from periodic table. How many protons are in manganese? The higher the associated electronegativity number, the more an element or compound attracts electrons â¦ RuO2 is stable. Rhenium atoms have 75 electrons and the shell structure is 2.8.18.32.13.2. Question: 8 Isotopes Of Rhenium Is Shown Below The Element Rhenium Is Used For Catalysis Of Many Organic Reactions. The rhenium used in the flashbulb that we talked about earlier was actually an alloy, or a mixture of two metals. Rhenium-185 has the atomic 75. Let x = the atomic weight of Re-185 and (371.9087 - x) = the atomic weight of Re-187.
