Answer

Mendeleeff's Periodic Law — The physical and chemical properties of elements are periodic functions of their atomic weights.

Mendeleeff's arrangement had elements with similar properties appearing at regular intervals. This phenomenon is called 'periodicity of properties' and the properties which repeat themselves at regular intervals are called 'periodic properties'. Some examples of periodic properties are atomic radius, ionisation potential, electron affinity, etc.
