Formula Conversion vs ELEMENTORUM

It is a formula conversion application. You can print a formula or a modified formula. You can save unmodified formulas to your phone's storage medium and then open it if necessary. Upgrading An application without an upgrade is limited to 24 formula conversions. If you want to convert the formula more than ten times, you must make an in-app purchase. Creating and opening a formula You can open the formula by clicking the first button on the toolbar. You can create a new formula using the symbols, symbols, numbers, and letters on the keyboard. You can change the font size of letters and symbols by pressing the "alp." Or "ALP." And "sym." Or "SYM." Buttons on the toolbar. If you wish, you can delete the characters by pressing the "del." Key. And use the arrows to move between the elements of the formula. Formatting the formula You can format the formula by first selecting the characters you want to change. The selection key is "Sel.", And you can then select by scrolling between the elements of the formula or by pressing the finger on the desired character. You can format the selected formula by pressing the second button on the toolbar from the back. You can change the font, font size, font, and font color Saving and printing the sample You can save the formula by pressing another button on the toolbar. Press the third button on the toolbar to print. If you want to delete the saved formulas, press the fourth button on the toolbar. Converting a formula When the formula is ready, you can publish parts of the formula. To publish part of a formula, select the item with the cursor. Press the fifth button on the toolbar to publish the formula. You can also print the converted formula by clicking the "Print" button. Zoom a formula If you want to increase or decrease the formula, press the third button on the back of the toolbar.

Learn the elements of the periodic table in a playful way. All chemical elements have a natural position in the periodic table, which are queried in a quiz-like manner in this ELEMENTORUM app. The tasks are designed so that you benefit from learning how professional chemists memorize the arrangement of the elements. And here's a secret: Very few chemists know ALL chemical elements and their positions in the periodic table by heart. However, what every chemist knows exactly are the main group elements such as H, O, N, C etc. Of the 9 levels in this app, the first 4 levels focus solely on the main group elements. Only then do the subgroup elements such as Co, Ni, Fe, etc. come. In ELEMENTORUM, the subgroup elements are added to the quiz questions in levels 5 to 7. And only the very diligent ones learn the lanthanides and actinoids by heart. But take on the challenge in levels 8 and 9 and try to solve all the tasks correctly. And here's another secret: No chemist learns the periodic table line by line, or row by row, or period by period. Chemists learn the periodic table from top to bottom, column by column, or group by group. And why? Because elements in the same column or group have the same or similar chemical properties. For example, the alkali metals Li, Na, K, Rb and Cs. Or the halogens F, Cl, Br and I. Or the noble gases He, Ne, Ar, Kr and Xe. So it simply makes more sense for a chemist's work to memorize the elements in groups than in periods. In the ELEMENTORUM app you are shown a section of the periodic table in each task, i.e. 3-4 rows (periods) and 3-4 columns (groups). The position of one element should be found. Orientate yourself on which elements are to the left and right of the element you are looking for, but focus in particular on the elements that are above and below. Then, with a little practice, you will be able to assign more and more elements to the correct positions and become a master of the periodic table.
