Name Origin: Derived from the spanish term platina del pinto, meaning “little silver of the pinto river.” Badges: Precious Metal, Noble Metal. Platinum can have 1-3 valence electrons, as it is in the transition metals group. Platinum is a transition metal in group 10, period 6, and the d-block of the periodic table. However, for the other groups, there is a fixed valency that those elements may have. The electrons in the 4d55s1 constitute its valence electrons. Here is a table of element valences. Electrons[e-]: 78. The outer shell of the Atom is referred to as the Valence shell. 6. the number of valence electrons in a Tellurium (Te) atom. In the periodic table, the elements are listed in order of increasing atomic number Z. Electron configuration of Platinum is [Xe] 4f14 5d9 6s1. Its electron configuration as an atom is [Ar]3d^5 4s^1, so it has 6 valence electrons. "An electron in one of the outer shells of an atom that takes part in forming chemical bonds." For #2, F has just one valence electron; O has just two. The chemical symbol for Platinum is Pt. It is highly resistant to chemical attack. 190 Pt, 192 Pt, 194 Pt, 195 Pt, 196 Pt, 198 Pt; EXPLORE THE GROUNDS. It has a melting point of 1768 degrees Celsius. Active 2 years, 5 months ago. Physically, platinum is heavy, soft, malleable (easy to work—only silver and gold are easier to shape), and DUCTILE (easy to draw into wires) and has a fairly high MELTING POINT . What are some common ions formed by your element? Remember, shells don’t neatly stack on top of each other, so the valence may not be the same as the total number of electrons in the outer shell. Ne has none. Hall of Fame hopeful accused of damning abuse allegations. Neutrons[N*]: 117. It is classified as a transition metal and placed in group 6 or d-block and period 5 of the periodic table of elements. 2a, and from the theoretical density of states for Pfc (8). Platinum is an extremely rare metal, occurring as only 5 ppb in the Earth's crust. Platinum is transition metal, they always have 2 valence electrons, because they grow penultimate layer.

The platinum arsenide, sperrylite (PtAs 2), is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario, Canada. Therefore, elements whose atoms can have the same number of valence electrons are grouped together in the periodic table of the elements.. The valence electrons for main group elements are those with the highest n … All elements within the transition metals group do not have specific valency. CITED FROM EXPLAINTHATSTUFF.COM electrongravity: 2.28 valence electrons: 1 Platinum is commonly used in jewelry, wire for conduction, vessels for laboratory use, dentistry, and electrical contacts. The most stable valence is one that fills or half-fills an atom’s electron shell. Only two define valence electron/s: "The electrons in the outermost shell of an atom determining chemical properties." It is more precious than silver but with prices more volatile than gold. 11.

For #1 I can see F has seven valence electrons. The work function for platinum is {eq}\rm 6.35\ eV {/eq}. Element: Platinum. We consider that the thermal effect of the valence fluctuation of the Pt mixed-valence state causes a red shift of the IVCT absorption edge and that the thermal effect of the hydrogen bond between the PtII complex ion and the PtIV complex ion causes a blue shift of the IVCT absorption edge. The most common valences are in BOLD. Its atomic mass is 95.96 grams per mole, and it has a density of 10.2 grams per centimeter cubed. the number of valence electrons in a Indium (In) atom. 39. the number of electrons in a neutral Yttrium (Y) atom. b) Find the cutoff frequency for platinum. Valence Electrons. Platinum, also, has a single valence electron. Platinum metal is silvery white and does not oxidise, properties that make it highly appealing for jewellery.
