This sample demonstrates many different methods of painting directly to a form to and creating ‘clickable’ regions. The project draws the Periodic Table and all associated properties with each element.
On top you find the Table of Mendeliev (of Mendeljef), beneath, the properties of the current selected element (inverted box in the table).
You can select a chemical element:
- using the cursor keys
- by clicking the element in the table
- using the popup-menu item : Go to element
- by clicking then Go to element button (binoculars)
The Presented Properties
| Average atomic mass | IonCharge | Oxidationnumber |
| Covalent radii ( E ) | Electro-negativity | 1st Ionisation potential ( in eV ) |
| Density ( 10e3 . kg / m3 ) | Specific gravition | Specific heat ( Joule / g .0C ) |
| Evaporation heat | Boiling point ( 0C ) | Melting point ( 0C ) |
| Fusion heat | Heat conduction | Electric conduction |
When you click one of these properties, they will be presented graphically in the table.>p
Oxidate Trap
Meaning
- 2 – acid oxide
- 8, 5 – predominantly acid amphoteric
- 3, 7 – amphoteric
- 9, 4 – predominantly basic amphoteric
- 1 – basic oxide
- 6 – state doesn’t exist, is onstable or badly defined
- * – approximate stoechimetry of the oxide
- ( ) – are rare
