The method of grouping the elements into different classes is known as periodic classification of elements. 2. We know by now that the elements are the basic units of all types of matter. In 1800, only 31 elements were known. By 1865, the number of identified elements had more than doubled to 63. At present 114 elements are known. WebEmpirical return periods are assigned to observed extreme values using an empricial rule where extreme values are ordered and ranked from the most extreme (1) to the least extreme (n), then exceedance probabilities are calculated (see the following sub-section), and return periods are calculated as multiples of a given return_period_size … define biohazardous waste
