The periodic table is a table of chemical elements that shows us the trends and characteristics of the elements. The periodic trends are a specific pattern of the major and minor elements.
- The trends are shown by the electronegativity, ionization energy, electronic affinity, ionic radius, atomic radius, and chemical reactivity. This trend arises from the changes in the atomic structure of the chemical elements.
- This pattern is based on the periodic laws and states that the chemical elements are put in order of increasing atomic number. However, they don't follow the symbols of elements.
Hence the option B is correct.
