What is periodic table ?
The periodic table is an organization of all known elements in order of increasing atomic number and repeating chemical characteristics.
They are organized in a tabular format, with a row representing an era and a column representing a group.
Elements are ordered in increasing atomic number order from left to right and top to bottom.
Elements of the same group will have the same valence electron configuration and, as a result, will have comparable chemical characteristics.
Elements are arranged in the periodic table based on various patterns. For example the element magnesium (Mg) A. has a higher atomic mass than the element sodium (Na).
Hence, option A is correct.
