Periodic table the periodic table is a table, where all known chemical elements are arranged they are organized on the basis of their atomic numbers, electrons and chemical properties they are organized on the basis of their atomic numbers, electrons and chemical properties. All the elements have been arranged in a table, called the periodic table, in order of their atomic numbers—the number of protons an element has in each of its atoms elements in the same group on the table have similar properties.

The periodic table of elements is familiar to anyone that ever entered a laboratory or classroom it has no rival in its ability to systematize and rationalize known chemical facts, predict new elements, or suggest fertile areas for further studies. Periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number—ie, the total number of protons in the atomic nucleus when the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their properties, in which elements in the same. Get the facts about element potassium (k)  from the periodic table find physical data, electron configuration, chemical properties, aggregation states, isotope data (including decay trees) as well as some historic information.
