give the diferentiation in the shortest way posible for periodic table and periodicity of properties in columns

The periodic table is a tabular arrangement of chemical elements, organized based on their atomic number, electron configuration, and recurring chemical properties. Elements are listed in order of increasing atomic number, which corresponds to the number of protons in an element's atomic nucleus. The table has rows called periods and columns called groups.

Periodicity of properties in columns, on the other hand, refers to the recurring trends observed in the properties of the elements. These trends are seen when elements are arranged in order of increasing atomic number. The most important trend is the increase in atomic size down a group (column) and the decrease in atomic size across a period (row). Other trends include variations in electronegativity, ionization energy, electron affinity, and metallic character.

In short, the periodic table is the physical representation of the elements and their properties, while periodicity refers to the observed trends in these properties across the table.
