In essence, periodicity is the guiding principle behind the organization of the modern periodic table. Elements within a group (column) display similar characteristics. The rows in the periodic table (the periods) reflect the filling of electrons shells around the nucleus, so when a new row begins, the elements stack on top of each other with simil...
Because of periodicity, you can tell from the periodic table that both sodium and lithium are highly reactive metals, with an oxidation state of +1. Similarly, you know beryllium is less reactive than lithium, but still a metal. Periodicity allows predictions for the behavior of elements that haven’t been synthesized in large enough amounts to stud...
Several element properties display periodicity. The key recurring trends are: 1. Electronegativity– Electronegativity is a measure of how readily an atom forms a chemical bond. Electronegativity increases moving left to right across a period and decreases moving down a group. Or, you could say electropositivity decreases moving left to right and in...
The periodicity of these properties follows trends as you move across a row or period of the periodic table or down a column or group: Moving Left → Right 1. Ionization Energy Increases 2. Electronegativity Increases 3. Atomic Radius Decreases 4. Metallic character decreases Moving Top → Bottom 1. Ionization Energy Decreases 2. Electronegativity De...
Scientists discovered periodicity in the 19th century. Lothar Meyer and Dmitri Mendeleev independently formulated Periodic Law in 1869. Chemists of this era arranged elements by increasing atomic weight, because the proton and atomic number had not yet been discovered. Even so, periodic tables of the day displayed periodicity. The reason for recurr...
