WebAug 28, 2024 · The less electronegative the element, the less stable the lone pair will be and therefore the higher will be its basicity. Another useful trend is that basicity decreases as you go down a column of the periodic table. This is because the valence orbitals increase in size as one descends a column of the periodic table. WebPeriodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element.They were discovered by the Russian chemist Dmitri Mendeleev in the year 1863.
