Elements are presented in increasing atomic number. The main body of the table is a 18 × 7 grid, with gaps included in to keep elements with similar properties together, such as the halogens and the noble gases. These gaps form four distinct rectangular areas or blocks. The f-block is not included in the main table, but rather is usually floated below, as an inline f-block would make the table impractically wide. The periodic table accurately predicts the properties of various elements and the relations between properties. As a result, it provides a useful framework for analyzing chemical behavior, and is widely used in chemistry and other sciences. You can pinch zoom and select each element to view their properties.Use 'One finger' to move the screen up/down/left/right on periodic table.Use 'two fingers/swipe' to get next element on details screen.Use 'one finger touch drag' to get sub details of element on Periodic table.
