Question

please explain the Trends of periodic table​

Answer 1

Answer:

Periodic trends arise from the changes in the atomic structure of the chemical elements within their respective periods (horizontal rows) and groups in the periodic table. These laws enable the chemical elements to be organized in the periodic table based on their atomic structures and properties. Due to the periodic trends, the unknown properties of any element can be partially known.

Several exceptions, however, do exist, such as that of ionization energy in group 3, The electron affinity trend of group 17, the density trend of alkali metals aka group 1 elements and so on.
