Search PubChem vs Periodic

The app allows to search compounds through PubChem and helps to keep information on solutions made of those compounds. I. Compounds Tab Search the open chemistry database 'PubChem' at the National Institutes of Health (NIH) for chemical compounds. The app helps to find a compound by name from the collection of more than 111 million compounds. It downloads and stores the molecular formula, weight, and structure. Compounds 1. Selecting the "Compounds" tab will present a list of compounds. - If there are any solutions made of a compound, a droplet will appear next to the compound's name. 2. When a compound is selected, a view with the detailed information will appear. Follow the instruction in "Details for a compound". 3. When the "+" button is selected, a view for search will appear. Follow the instruction in "Search for a compound". Details for a compound 1. Click "Compounds" to return back to the table of compounds. 2. Click the magnifier icon to open the compound's PubChem page in the user's default web browser. 3. Click the trashcan icon to delete the compound. This function may not be available if there is a solution made of the compound. 4. Click one of the solutions made of the compound to display the information. See "Details for a solution" below. 5. Click "3D" to display a 3D structure. Use pan and pinch gestures to rotate and zoom the scene. Search for a compound 1. Select "Compound Name" ("CID") and type a compound name (PubChem CID). 2. Click "Search" to connect to PubChem. An activity indicator will appear until the search is finished. - If the search succeeds, the downloaded information will appear. - If the search fails, an alert will appear. 3. Click "Save" to store the information about a compound. 4. Click "Cancel" to dismiss the scene. II. Solutions Tab Choose compounds downloaded from PubChem and make a solution. The app allows to record a list of compounds with amounts dissolved in a solution. For the saved solutions, the app displays their compositions in gram and mol. Solutions 1. Selecting the "Solutions" tab will present a list of solutions. 2. When a solution is selected, a view with the detailed information will appear. Follow the instruction in "Details for a solution". 3. When the "+" button is selected, a view for search will appear. Follow the instruction in "Making a solution". Details for a solution 1. Click "Solutions" to return back to the table of compounds. 2. Click the 'action' icon to share a csv file containig the information about the solution. 3. Click the trashcan icon to delete the solution. 5. Choose the unit among gram, mg, mol, and mM. 6. Select one of compounds to display its structure and formula. See "Mini details for a compound" below. Making a solution 1. Click "Add Compounds" to bring a collection of compounds. See "Compounds collection" below. 2. The names of the compounds selected from "Compounds collection" will be displayed as “Solution Label”. A user can edit “Solution Label”. 3. The unit for the amount can be chosen among gram, mg, mol, and mM. 4. The amount may be entered. 5. Click "Save" to create and add a new solution. 6. Click "Cancel" to dismiss the scene. Compounds collection 1. Select or deselect compounds by clicking the images of compounds. 2. Selected compounds will be displayed. 3. Click "Done" to return back to "Making a solution". 5. Click "Cancel" to dismiss the scene.

The PeriodicTableElements is an elegant app that is interactive and fun. Easy to use, easy to understand, simple and effective. It shows the periodic table of elements in variety of ways 1) Classic grid with name that is color coded. You can configure it to look however you like. 2) Visually appealing electron distribution. 3) Visually appealing Lewis dot structure. 4) List that can be sorted based on different element properties like group, period, category etc. These awesome periodic tables can be shared by simple double click anywhere on the table. It is possible to copy the periodic table diagrams as high quality SVG xml. Drag your finger on the periodic table canvas to update elements automatically or tap on an element to see more details. Tap on an element and all the rest of the related elements are highlighted. Details of a selected element is shown in a beautifully drawn animated element. Tap on the animated element and you will see more details that can also be shared. Tapping on the list element will navigate you to a page that shows details of the element. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning chemistry. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!
