Periodic Properties

The properties of elements are periodic function of their atomic numbers. Hence when elements are arranged in the order of increasing atomic number, the characteristic properties of elements reappear at regular intervals. Such characteristic properties of elements which reoccur at definite intervals in periodic table are called Periodic Properties. There are many periodic properties like valency, atomic size, ionic size, ionisation energy, electron affinity, electronegativity etc. These periodic properties can be discussed in the next post.
