In the periodic table, the reactivity of the halogens that are found in Group 17 decreases as you go down the column of elements in this group. The first element of the group is fluorine, and it has the highest reactivity. The other elements in this group are chlorine, bromine, iodine, and astatine.


Electronegativity increases left to right and bottom to top. Fluorine has the highest and cesium has the lowest.


Periodic trends affect bonding due to the arrangement of the elements on the periodic table. The periodic table only includes chemical elements.


periodic trends are the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements.


it is important to know the trends in the periodic table so you can use it more easily



Electronegativity Trends, Ionization Energy Trends, Electron Affinity Trends, Atomic Radius Trends, Melting Point Trends, Metallic Character Trends.

Periodic trends illustrate how some elements are very reactive while others are stable.


For periodic trends we will examine1- Electronic configuration 2- Ionization energy 3- Atomic radius


The periodic trends that arise from the arrangement of the periodic table provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or period and the periodic nature of the elements.




People who wish to find the answers to the trends in the periodic table will not find them online. They will have to review the course study materials to obtain the answers.
