Rhenium is a chemical element with atomic number 75 which means there are 75 protons and 75 electrons in the atomic structure. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. Sketch the orbital diagram of the valence shell of a bromine atom (ground state) on the energy axis provided. Atomic spectrum . ... Two factors contribute to the high hardness of ReB 2: a high density of valence electrons, and an abundance of short covalent bonds. These atomic orbitals are close enough in energy that the derived bands overlap, so the valence electrons are not confined to a specific orbital. In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. occ. See more. The magnetic moment of 1.79 BM corresponding to 1 unpaired electron, and esr evidence showing that … based on the electronic configurations of the metals , they have valence electrons present in their valence shell which are easily available for donation so that they can attain stable electronic configuration and thus they are considered as metals. Most of the ores mined for Rhenium come from Chile and it is a very rare metal. Rhenium diboride (ReB 2) is a synthetic superhard material. It was named after the river Rhine in Germany. 6-447.405.

It was one of the last elements to be discovered that had a stable isotope at such a large size. tweet; Previous: Osmium Os (Element 76) of Periodic Table. Also, shells don't stack neatly one on top of another, so don't always assume an element's valence is determined by the number of electrons in its outer shell. 62. Synthesis, crystal structure, and reactions of the 17-valence-electron rhenium methyl complex [ η ... Organometallic complexes with 17 valence electrons have numerous important physical and chemical properties that are not shared by their 18 and 16-valence-electron counterparts . Once again, the number of d valence electrons per atom is a good predictor of melting point (see Table I): Along both the 4d and 5d series, the maximum melting point is reached for about 4 valence electrons per atom (just one less than for Re). A lithium atom has one outer shell electron, so it’s usual valence is +1, but it can lose the electron and have a valence of -1. Rhenium is a silvery-white, heavy, third-row transition metal in group 7 of the periodic table. If an ionic charge is known, for example, +2, then it can be assumed that the formula for the oxide would be RhO. It has a melting point of 3186 degrees Celsius. Coordination and organometallic complexes. The metal structure can be considered, therefore, it consists of a set of positive ions, tightly packed and surrounded by a number of free electrons (valence electrons), which form a kind of electronic fluid called sometimes sea electrons. The valence electrons of transition metals occupy either their valence ns, (n − 1)d, and np orbitals (with a total capacity of 18 electrons per metal atom) or their ns and (n − 1)d orbitals (a total capacity of 12 electrons per metal atom).
