Features

PocketChemistry consists of several tools, each of which has a well-defined purpose. Integrating the tools in one application provides extra benefits, such as similar user interface or quick access to any of the tools. The main tools are: periodic table, constants database, equation balancer, molecular mass calculator and property plot.

-----------------------------------------

Periodic table

Displays the periodic table. You can choose how the table is displayed, including whether you want it colored by element block or family, whether you want a wide or a narrow table, and what properties you want to be displayed. You can tap an element to see its properties. You can save all settings in a preset for quick access. View screenshots.

Available properties:

  1. Name
  2. Symbol
  3. Number of protons
  4. Number of neutrons
  5. Element block
  6. Element family
  7. Electron configuration
  8. Electron levels
  9. Crystal structure
  10. Atomic radius
  11. Atomic volume
  12. Ionic radius
  13. Covalent radius
  14. Mass
  15. Melting point
  16. Boiling point
  17. Density
  18. Enthalpy of fusion
  19. Enthalpy of vaporization
  20. Electronegativity
  21. Oxidation states

-----------------------------------------

Constants database

Lets you view over 80 physical and chemical constants, divided into 4 categories, which in turn are divided into sub-categories. Each entry includes constant name, symbol, value, units, and over half of all entries include a formula which can be used to calculate the constant from other constants. You can show, hide and resize columns. View screenshots.

Available categories:

  1. Universal constants
  2. Electromagnetic constants
  3. Nuclear constants (divided in two categories for speed)
  4. Physico-chemical constants

-----------------------------------------

Equation balancer

Balances chemical equation by finding correct coefficient for each molecule in the equation. This tool can balance any equation that has solutions, including equations which have infinitely many non-equivalent solutions. Formulae are displayed in the correct notation (see screenshots). You can enter formulae all in lowercase without any spaces, and elements will be still recognized correctly, with extremely rare exceptions. For example, you can enter kmno4, and you will see KMnO4 displayed. View screenshots.

-----------------------------------------

Molecular mass calculator

Calculates the mass of any molecule that you enter. The same capitalization algorithm is used here to speed up entry. Just like equation balancer, this tool performs calculations in a split second. The calculator takes the accuracy of the element masses in the database into account, and displays the final mass together with its accuracy. View screenshots.

-----------------------------------------

Property plot

Lets you plot a graph of any numerical property against any other numerical property. You can apply a filter to values of both axes, and you can change some display parameters. The tool lets you zoom and scroll freely. You can save up to three plots as presets for later use. View screenshots.

-----------------------------------------

Other

There are also a couple of other tools available. You can use the Find tool to quickly find an element by entering one or two first letters in its name or symbol (screenshots). The Electrochemical series tool displays a table of metals ordered by their activity (screenshots). The Element property viewer displays all properties of an element (screenshots). Integrated help system will tell you how to use the tools (screenshots).
