FAQs on The Making of Periodic Table Video Lecture - Chemistry for JEE Main & Advanced

1. How was the periodic table created?
Ans. The periodic table was created based on the observations and experiments conducted by Dmitry Mendeleev, a Russian chemist, in 1869. He organized the elements known at that time into a table based on their atomic mass and chemical properties, noticing a periodic pattern in their properties.
2. What is the significance of the periodic table?
Ans. The periodic table is significant as it provides a systematic way to organize and classify all the known elements. It helps scientists understand the relationships between elements, predict their chemical behaviors, and discover new elements or properties based on their position in the table.
3. How are elements arranged in the periodic table?
Ans. Elements in the periodic table are arranged in order of increasing atomic number, which is the number of protons present in the nucleus of an atom. They are organized into rows called periods and columns called groups. Elements within the same group share similar chemical properties, while elements in the same period have similar electron configurations.
4. Who contributed to the development of the periodic table?
Ans. In addition to Dmitry Mendeleev, several other scientists made significant contributions to the development of the periodic table. These include Henry Moseley, who arranged the elements by atomic number rather than atomic mass, and Glenn T. Seaborg, who discovered many new elements and expanded the table to include the actinides and lanthanides.
5. Can the periodic table change over time?
Ans. Yes, the periodic table can change over time. New elements can be discovered, and their properties can be better understood, leading to revisions in the table. For example, elements 113, 115, 117, and 118 were officially added to the periodic table in 2016. As scientific knowledge advances, the periodic table may continue to evolve to accommodate new discoveries.
