There are 2 valence electrons in Radium. The platinum–platinum bonds are as short as 2.70 Å, a value below the corresponding one as was found in Krogmann's salt K 2 [Pt(CN) 4]Cl 0.32 ⋅2.6H 2 O (2.88 Å) , . Platinum is a transition metal in group 10, period 6, and the d-block of the periodic table. An atom with a closed shell of valence electrons (corresponding to an electron configuration s 2 p 6) tends to be chemically inert. Don't forget to put the atomic symbol (Pt) in this case in the middle. If we agree that the valence electrons are ones involved in chemical bonding, and that platinum has been shown to have an oxidation state as high as +6, then we can suggest that platinum can have as many as six valence electrons. The chemical symbol for Hydrogen is H.. With a standard atomic weight of circa 1.008, hydrogen is the lightest element on the periodic table. Technically speaking since it has 2 6s electrons and 7 5d electrons, it has 9 valence electrons. Electrical conductivity in metals is a result of the movement of electrically charged particles. Platinum Electronic configuration. An atom of Platinum in the gas phase, for example, gives off energy when it gains an electron to form an ion of Platinum. The trends across the transition metals are due to electrons filling an inner d-subshell (here, within the 5th ring), shielding the outer (valence) electrons from the … However, for the other groups, there is a fixed valency that those elements may have.
Platinum is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. In the case of Palladium the valence electrons is 2,3,4. The configuration of these electrons follows from the principles of quantum mechanics. Here again, analyzing the band structure leads to a deeper understanding of the bonding. It is in Group 10 and has 78 electrons. Sign up to join this community. In addition technical terms are linked to their definitions and the menu contains links to related articles that are a great aid in one's studies. Name: Platinum Symbol: Pt Atomic Number: 78 Atomic Mass: 195.078 amu Melting Point: 1772.0 °C (2045.15 K, 3221.6 °F) Boiling Point: 3827.0 °C (4100.15 K, 6920.6 °F) Number of Protons/Electrons: 78 Number of Neutrons: 117 Classification: Transition Metal Crystal Structure: Cubic Density @ 293 K: 21.45 g/cm 3 Color: silverish Atomic Structure Comprehensive data on the chemical element Platinum is provided on this page; including scores of properties, element names in many languages, most known nuclides of Platinum. Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Transition metals and heavier elements are exceptions and are more stable when they have more electrons in their outer shell. Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top Home ; Questions ; Tags ; Users ; Unanswered ; Anomalous electronic configuration of platinum. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure. Platinum is an extremely rare metal, occurring at a concentration of only 0.005 ppm in Earth's crust. These electrons determine the … Now let's check the facts about Palladium... Palladium Overview Palladium Valence Electrons 2,3,4 Atomic Number 46 Learn more about the atomic number. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.
