Question

What are the properties of periodic table ​

Answer 1

Answer:

The periodic table is arranged according to periodic properties in terms of ionization energy, electronegativity, atomic radius, electron affinity, and metallic character. The periodic table arranges the elements by periodic properties, which are recurring trends in physical and chemical characteristics.

Answer 2

Answer:

=> In the Modern Periodic Table, The Period Number is Equal to the No of Shells of an Atom.

=> Group No. { 1-2 } :- The Electrons in the Valence Shell.

Group No. {13 - 18 } :- 10 + Electrons in the Valence Shell.

=> On moving across a Period, the No of electrons in the outermost shell increases. Due To this, Atomic Radius Slowly Decreases across a period due to the increase in Effective Nuclear Charge.

=> All the Elements in a Group has Same No. Of Valence Electrons and the Shell No increases down a group.
