The table is color-coded to show the chemical groupings. Small symbols pack in additional information: solid/liquid/gas, the color of an element, common in the human body, common in the earth's crust, magnetic metals, noble metals, radioactive, and rare or never found in nature.
ChemWindow is a chemical structure drawing molecule editor and publishing program now published by John Wiley & Sons as of 2020, [1] originally developed by Bio-Rad Laboratories, Inc. [2] [3] It was first developed by SoftShell International in the 1990s. [4]

ACD/ChemSketch allows for both basic structure drawing and importation of 3D and 2D .MDL files from other molecular modelling programs. ChemSketch has been favorably compared to other molecular modelling software, especially ChemDraw, based on its ability to display a wide range of structural components and the ease of creating complex structures quickly.

PubChem can be accessed for free through a web user interface. Millions of compound structures and descriptive datasets can be freely downloaded via FTP. PubChem contains multiple substance descriptions and small molecules with fewer than 100 atoms and 1,000 bonds. More than 80 database vendors contribute to the growing PubChem database. [2]
Images composed of simple shapes, lines, and letters such as those below should be recreated using vector graphics as an SVG file. These have a number of advantages, such as making it easier for subsequent editors to edit them, enabling arbitrary scaling at high quality, and sharp high-resolution renderings for print versions.
MDL introduced specifications for chemical file formats, including the molfile (.mol), and structure/data file (.sdf) which were subsequently placed in the public domain and have become standards for representing structures in 2-D drawings and for transferring such information with associated data, for example identifiers, chemical names and substance properties.
