Computing: Free Pascal Programming

Graphical representation of the atomic structure.

Download Atoms desktop application (Windows 64bit) Download Atoms source code (Lazarus/Free Pascal)

Description: Simple graphical representation of the atomic structure of periodic table atoms, as well as of their isotopes and ions. The nucleus is drawn as a mass of colored disks (for the protons and neutrons), the electrons are drawn onto circles around the nucleus, where each of these circles represent a given shell. Entering a specific atomic mass number for a given element allows to draw the structure of non-periodic-table isotopes, entering a charge allows to do it for ions. The number of electrons in each shell is counted after filling the subshells following the Aufbau principle (removal of electrons for anions correctly considering the particular energy situation for transition metals and inner transition metals).
Help concerning the atomic structure as well as help how to use the application is included.

Free Pascal features: Canvas drawings. String grids. Reading data from a text file (classic Pascal). Records and arrays of records (classic Pascal).
