Web2. Define period trends. Answer: Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity. ... WebNov 3, 2024 · Electron affinity tends to increase (as in more energy is released when an electron is added to an atom) as you move up a group on the periodic table. Nobles gases have an electron affinity of approximately zero. There is a tendency for electron affinity to increase as you move left to right across a period. WebIn the d-block, you have many competing factors such as then need to have a full s and p, to energetic nuances due to the d subshell being partially full, and all these affect the electronegativity. Thus, in the d-block you don't have a clear periodic trend for electronegativity as you do in the s and p blocks. herschel backpacks pentagon city

WebMar 2, 2024 · Electron affinity follows a trend on the periodic table. It increases moving down a column or group and also increases moving from left to right across a row or period (except for the noble gases). The value may be either positive or negative. A negative electron affinity means energy must be input in order to attach an electron to the ion. WebAn element's first ionization energy is the energy required to remove the outermost, or least bound, electron from a neutral atom of the element. On the periodic table, first ionization energy generally increases as you move left to right across a period.
