Periodic Table

Portable version of Dmitri Mendeleev's periodic table of elements available for iPhone and iPad platforms. You can access to all table elements scrolling opportunely the view in all directions. Tapping on an element it will show in the upper part of the display the specific physical data of the selected element. The slider just under the selected element icon, allow you to select a temperature in the range [0 K, 6000K] and consequently see the physical state of the selected element changing [solid, liquid, gas or unknown].

The application also implement a chemical formula weight calculator. You need just to type the chemical formula in the text box and press "done" on the keyboard then the result of the calculation will be displayed. At today only expanded formulas are supported with no support for formulas with round or square brackets for grouping sub-molecules. The displayed spinning will allow you to select a chemical molecule from thousands already stored in the app itself and with automatic update of the weight.

Tapping on the displayed selected element, the app try to connect the device to internet opening a browsing session and looking for "element name" as target.

Tapping on the application icon available on the bottom left of the scrolling view, the app try to connect the device to internet opening a browsing session of the "PeriodicTable" support web site.

Periodic Table v1.0 (May 7th 2014)

- First release.

Known bugs

1. ...bugs are coming, just wait...
2. valence : Orbital : the related text string length does not use all available space : All versions;
3. Element with three characters are not recognised properly in the molecular weight calculator : All versions.
4. The search function of the chemical formula text box reports 'unknown' if the text is found in a formula with different string length : All versions.
5. Chemical formula that includes Zr (Zirconium) shows wrong results because the symbol is currently defined as Zc that is wrong.

Errata

1. benzoyl peroxide : C14H10O14 ==> C14H10O4 : All versions.
2. Francium (Fr) : wrong atomic weight : All versions.
3. Livermorium (Lv) : wrong atomic weight : All versions.
4. Zirconium (Zr) : wrong atom symbol Zc : All versions.

Periodic Table v1.1 (May 27 2014)

- Fixed known bugs #1, #2;

- Fixed known errata #1, #2, #3;

- A double tap into the temperature box allows you to change the measurement unit cycling among K, °C, °F;

- Typing the chemical synonym in the editable text box activates the search in the picker view list and if it match with something similar, the picker list scrolls to that new position;

- The element buttons are now highlighted when pressed;

- The temperature slider drives changes of the temperature colour depending on the selected element melting and boiling point and now also of the physical state colour in the selected atomic element button changes coherently;

- Memory warning will pop-up in case the system determines that the amount of available memory is low.

Periodic Table v1.2 (...coming soon)

- A double tap into the molecular weight box allows to view the calculation details in a tableview, atom per atom, as result of the calculated total molecular weight. The full text of the tableview can also be sent by email pressing the related button that open an email client session.

- The temperature slider now drives changes of the temperature colour also in all elements of the periodic table: gray -- melting and boiling temperature not available, black -- solid state, blue -- liquid state and red -- gas state;
