plz tell me long answer for Impact of periodic table on humans
Answers
Answer:
The periodic table is one of the most important tools in the history of chemistry. It describes the atomic properties of every known chemical element in a concise format, including the atomic number, atomic mass and relationships between the elements. Elements with similar chemical properties are arranged in columns in the periodic table.
The periodic table can be used to identify the matter already discovered by mankind. However, if new matter is discovered, then the atomic structure of the new matter can be compared to the elements in the table in order to classify the new material. Scientists can use the data in the table to figure out how the new matter may behave or what elements to which the new matter may be similar through this comparison.
Historical Perspective
Scientists can use the information in the periodic table to know when elements have been acted upon in some way. For instance, if scientists know that the basic form of an element has a particular number of neutrons, then they know that something has to have happened to the element if an isotope (an atom with the same number of protons but a different number of neutrons than the base element) is discovered. They may not know exactly what caused the isotope to form, but they can know with certainty that something did occur. This gives historical perspective.
