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.
Why is the periodic table such a useful tool for chemists? Atoms in the same group on the periodic table tend to have similar physical and chemical properties. This is because they have the same number of electrons in their outer energy levels. Scientists can use this information to predict how atoms will react with each other.
