Get the facts about element Silicon (Si) [14] from the periodic table. Find physical data, electron configuration, chemical properties, aggregation states, isotope data (including decay trees) as well as some historic information.
For example, the two common isotopes of carbon, 12 C and 13 C, have 6 and 7 neutrons, respectively. The abundance of each isotope depends on the source of materials. For relative abundances of isotopes in nature, see reference on Atomic Weights and Isotopic Compositions.
17 maj 2014 · Here is a list of elements of the periodic table, their atomic numbers, and element symbols. The list is ordered by increasing atomic number, which is the number of protons in an atom of that element. Each element has a symbol, which is a one- or two-letter abbreviation of its name.
Although the first four elements of group 14 form tetrahalides (MX 4) with all the halogens, only fluorine is able to oxidize lead to the +4 oxidation state, giving PbF 4. The tetrahalides of silicon and germanium react rapidly with water to give amphoteric oxides (where M is Si or Ge):
