WebSep 14, 2024 · Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. WebThe real development in the periodic table took place after the development of Mendeleev periodic table. He gave a law which states that “The properties of an element are the periodic function of their atomic masses”. He arranged elements in periods (horizontal rows) and groups (vertical columns) in the increasing order of atomic weights. jofra archer current teams

WebFeb 6, 2024 · Ionic Radius and Period It might seem counterintuitive that the size of an ion would decrease as you add more protons, neutrons, and electrons in a period. Yet, there's an explanation for this. As you move across a row of the periodic table, the ionic radius decreases for metals forming cations, as the metals lose their outer electron orbitals.
