Modify Elements and Molecules
- Electrons around the element symbol can be moved around the symbol by clicking once on the electron or electron pair to select it and then clicking a second time and dragging the electron(s) around the circular guide to its new location.
- Electrons can be added to an existing element by clicking on either Single Electron or Electron Pair on the left and then clicking on the circular guide around the element to place it.
- A charged ion can be represented by altering the number of valence electrons, adding brackets around the element and electrons, and then adding a positive or negative charge to the top right of the brackets.
- Brackets can be placed by selecting Brackets from the right side and then clicking the center point of where the brackets should be located.
- Brackets can be moved together by selecting either bracket and then dragging the brackets as a pair to their new location. Brackets can be moved horizontally independent of one another by dragging the one bracket to the side.
- Brackets can be resized by selecting either bracket and then using the handles in the corners to and change size. Note that the brackets are resized together no matter where they are located on the canvas.
- Charges can be changed by clicking on the charge symbol on the canvas. The positive charge rotates through +, 2+, 3+, 4+, 5+, 6+, and 7+. The negative charge rotates through –, 2–, 3–, 4–, and 5–.
- Bonds can be added between elements by clicking on the type of bond (single, double, double dashed, and triple), clicking on the first element to bond and then clicking on the second element to bond. Bonds will try to stay positioned between the elements even if you relocate the elements. Bonds can be changed be clicking on the bond on the canvas and they rotate through the 4 types of bonds available.
- You can group any number of the items on the canvas by clicking the select button and the dragging the selection around the items to group. Groups can also be ungrouped or duplicated by right clicking (long pressing on the iPad) on the group and the selecting the desired action.
