THE PERIODIC TABLE - History & Periodic Properties

THE PERIODIC TABLE - History & Periodic Properties

The periodic table, also known as the periodic table of (the) elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. It is widely used in chemistry, physics, and other sciences, and is generally seen as an icon of chemistry. It is a graphic formulation of the periodic law, which states that the properties of the chemical elements exhibit a periodic dependence on their atomic numbers.

The course discusses about Periodic Table in detail for a High School student starting from history to periodic properties like Atomic radius, metallic & non-metallic character, ionization potential, electron affinity & electronegativity.

Supporting concepts like K,L,M,N electronic configuration, valence electrons & valency are also included.

The periodic table continues to evolve with the progress of science. In nature, only elements up to atomic number 94 exist; to go further, it was necessary to synthesise new elements in the laboratory. Today, all the first 118 elements are known, completing the first seven rows of the table, but chemical characterisation is still needed for the heaviest elements to confirm that their properties match their positions.

In the end, there is an assignment on the topic taught which has 12 MCQ questions.
