Methods that can be used to improve adherence can be grouped into four general categories: patient education; improved dosing schedules; increased hours when the clinic is open (including evening hours), and therefore shorter wait times; and improved communication between physicians and patients.
The periodic table is the most important chemistry reference there is. It arranges all the known elements in an informative array. Elements are arranged left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass.
A more detailed electronic introduction and explanation of the periodic table. 1  The idea of the Periodic Table is to arrange the elements in a way that enables chemists to understand patterns in the properties of elements, AND be able to make predictions about the properties of elements and their compounds, but some reminders first.
