2. Structural formula - Wikipedia

   en.wikipedia.org/wiki/Structural_formula

   Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are possibly arranged in the real three-dimensional space.

3. Molecular graph - Wikipedia

   en.wikipedia.org/wiki/Molecular_graph

   In some important cases (topological index calculation etc.) the following classical definition is sufficient: a molecular graph is a connected, undirected graph which admits a one-to-one correspondence with the structural formula of a chemical compound in which the vertices of the graph correspond to atoms of the molecule and edges of the ...

4. Table of nuclides - Wikipedia

   en.wikipedia.org/wiki/Table_of_nuclides

   A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.

5. Chemical structure - Wikipedia

   en.wikipedia.org/wiki/Chemical_structure

   The methods by which one can determine the structure of a molecule is called structural elucidation.These methods include: concerning only connectivity of the atoms: spectroscopies such as nuclear magnetic resonance (proton and carbon-13 NMR), various methods of mass spectrometry (to give overall molecular mass, as well as fragment masses).Techniques such as absorption spectroscopy and the ...

6. Molecular graphics - Wikipedia

   en.wikipedia.org/wiki/Molecular_graphics

   A water molecule drawn with a shaded electrostatic potential isosurface. The areas highlighted in red have a net positive charge density, and the blue areas have a negative charge. In some models, the surface of the molecule is approximated and shaded to represent a physical property of the molecule, such as electronic charge density. [39] [40]

   Making a budget doesn’t have to be a chore. Take the 50/30/20 rule, which provides a simple budgeting framework: Split your after-tax income into three buckets: 50% for needs, 30% for wants, and ...

8. Periodic table - Wikipedia

   en.wikipedia.org/wiki/Periodic_table

   The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows ("periods") and columns ("groups"). It is an icon of chemistry and is widely used in physics and other sciences.
