Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character.

In chemistry, periodic trends are specific patterns present in the periodic table that illustrate different aspects of certain elements when grouped by period and/or group. They were discovered by the Russian chemist Dmitri Mendeleev in 1863.

Periodic trends are specific patterns observed among the chemical elements of the periodic table. These observed patterns allude to the changes in atomic structure, including size and radius, as well as properties of the elements.

Periodic Table Trends: The following trend in periodic properties of elements is observed: Atomic size Trends: The distance between the centre of the nucleus and the outermost shell of an atom is known as the atomic radius. In a group the atomic size increases due to the addition of shells as we move from one period to another.

Periodic trends in atomic size, ionization energy, and electronegativity are described. The trend of valence electrons that determine the chemical characteristics of an element and their …
