Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. Many of the physical and chemical properties of elements can be correlated to their unique electron configurations. 3) 2-8-6 D: Atomic number of neon is 10 and its electronic configuration is . Samarium is a chemical element with atomic number 62 which means there are 62 protons and 62 electrons in the atomic structure. Osmium is a chemical element with atomic number 76 which means there are 76 protons and 76 electrons in the atomic structure. Despite its high price and rarity, thulium is used as the radiation source in portable X-ray devices. The chemical symbol for Antimony is Sb. Let look at the successive IE for carbon and I would leave oxygen for you to do the analysis. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding metallic chromium to form stainless steel. Electron Configuration Like in every other element apart from Hydrogen, in Oxygen's first electron shell, there are two electrons, filling it to the maximum limit. In the formula for ozone the central oxygen atom has three bonds and a full positive charge while the right hand oxygen has a single bond and is negatively charged. The chemical symbol for Helium is He. The chemical symbol for Indium is In. The maximum electrons that can be carried by the sub-shell S is 2, by P is 6, by D is 10, and the F sub-shell can carry 14. We have also distinguish between the possible and common oxidation states of every element. The chemical symbol for Osmium is Os.
