  2. CPK coloring - Wikipedia

    en.wikipedia.org/wiki/CPK_coloring

    Column J is the color scheme used by the molecular visualizer Jmol. [9] Column R is the scheme used by Rasmol; when two colors are shown, the second one is valid for versions 2.7.3 and later. [9] [10] Column P consists of the colors in the PubChem database managed by the United States National Institute of Health.

  3. Electronic band structure - Wikipedia

    en.wikipedia.org/wiki/Electronic_band_structure

    So the expansion can be written as: = where K = m 1 b 1 + m 2 b 2 + m 3 b 3 for any set of integers (m 1, m 2, m 3). From this theory, an attempt can be made to predict the band structure of a particular material, however most ab initio methods for electronic structure calculations fail to predict the observed band gap.

  4. Extended periodic table - Wikipedia

    en.wikipedia.org/wiki/Extended_periodic_table

    This small radius and high weight cause it to be expected to have an extremely high density of around 46 g·cm −3, over twice that of osmium, currently the most dense element known, at 22.61 g·cm −3; element 164 should be the second most dense element in the first 172 elements in the periodic table, with only its neighbor unhextrium ...

    en.wikipedia.org/wiki/Unit_of_time

    One trillionth of a second. nanosecond: 10 −9 s: One billionth of a second. Time for molecules to fluoresce. shake: 10 −8 s: 10 nanoseconds, also a casual term for a short period of time. microsecond: 10 −6 s: One millionth of a second. Symbol is μs millisecond: 10 −3 s: One thousandth of a second. Shortest time unit used on ...

  6. List of chemical elements - Wikipedia

    en.wikipedia.org/wiki/List_of_chemical_elements

    A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...

    en.wikipedia.org/wiki/GarageBand

    On November 1, 2011, Apple introduced GarageBand for iOS 1.1, adding support for the iPhone and iPod Touch, among other features. These included the ability to create custom 3 4 and 6 8 time signatures, and exporting in AAC or AIFF format. [17] On March 7, 2012, Apple updated GarageBand to 1.2, adding support for the third-generation iPad. It ...

  8. Schrödinger equation - Wikipedia

    en.wikipedia.org/wiki/Schrödinger_equation

    The equation given by Schrödinger is nonrelativistic because it contains a first derivative in time and a second derivative in space, and therefore space and time are not on equal footing. Paul Dirac incorporated special relativity and quantum mechanics into a single formulation that simplifies to the Schrödinger equation in the non ...

  9. Livermorium - Wikipedia

    en.wikipedia.org/wiki/Livermorium

    [4] [96] The electron of a hydrogen-like livermorium atom (oxidized so that it only has one electron, Lv 115+) is expected to move so fast that it has a mass 1.86 times that of a stationary electron, due to relativistic effects. For comparison, the figures for hydrogen-like polonium and tellurium are expected to be 1.26 and 1.080 respectively.
