Fluorine is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. Neptunium is the first transuranic element. Thorium is moderately hard, malleable, and has a high melting point. The chemical symbol for Iodine is I. Iodine is the heaviest of the stable halogens, it exists as a lustrous, purple-black metallic solid at standard conditions that sublimes readily to form a violet gas. Discoverer: Davy, Sir H. and Thénard, L.-J. As an approximate rule, electron configurations are given by the Aufbau principle and the Madelung rule. Lawrencium is the final member of the actinide series. This sample weighted about 0.01µg and was measured using a special magnetic-typ… Uranium is weakly radioactive because all isotopes of uranium are unstable, with half-lives varying between 159,200 years and 4.5 billion years. © 2019 periodic-table.org / see also Curium is a hard, dense, silvery metal with a relatively high melting point and boiling point for an actinide. The chemical symbol for Silver is Ag. Why is the following electron configuration incorrect? Determine what elements are denoted by the following electron configurations: a. In nuclear industry, especially natural and artificial samarium 149 has an important impact on the operation of a nuclear reactor. Mendelevium is a metallic radioactive transuranic element in the actinide series, it is the first element that currently cannot be produced in macroscopic quantities. The bulk properties of astatine are not known with any certainty. Significant concentrations of boron occur on the Earth in compounds known as the borate minerals. The chemical symbol for Caesium is Cs. The chemical symbol for Holmium is Ho. If you don’t have a chart, you can still find the electron configuration. The chemical symbol for Dysprosium is Dy. The chemical symbol for Iridium is Ir. Electron Configuration Number of Neutrons Melting Point Boiling Point Date of Discovery Crystal Structure. Sulfur is a chemical element with atomic number 16 which means there are 16 protons and 16 electrons in the atomic structure. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Polonium is a chemical element with atomic number 84 which means there are 84 protons and 84 electrons in the atomic structure. In the space below, write the shorthand electron configurations of the following elements: a. cobalt [Ar] 4s23d7 b. silver [Kr] 5s24d9 c. tellurium [Kr] 5s24d105p4 d. radium [Rn] 7s2 e. francium [Rn] 7s1 2. The configuration of these electrons follows from the principles of quantum mechanics. When an electron is added to a … However, if you have data that you would like to share with this EELS community, please feel free to use the link below to submit your data for consideration. Selenium is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. Neptunium metal is silvery and tarnishes when exposed to air. That means it has 13 valence electrons; but you must take into consideration that the maximum number of valence electrons any element can have is 8; so 13 - 8 = 5.
