You are watching: What is the zigzag line on the periodic table called
In addition to Pritt Balagopal"s answer, in i beg your pardon he has actually clarified the patterns in metallic character throughout the periodic Table, i would also like to describe why the metalloids occur in a zig-zag fashion.
Firstly, i would favor to again clarify that it is maybe a coincidence that the metalloids begin from boron, no carbon or any type of other non-metal in the period. My guess can be the start of electron occupation the the p subshells. Note that boron has one electron in its p subshell. Thus, its chemical properties begin to readjust to become an ext non-metallic in nature.
Diagonal relationships is a usual occurrence in the routine Table. However, it is frequently used to describe the relationship between two aspects which space diagonal to each other, no a entirety line that them. Thus, ns would prefer to clarification again that this is simply my conjecture, no what is the true reason. However I think this should be part of the exactly explanation together it is logically sound.
This site supplies a much more in-depth explanation as to why diagonal relationship occur:https://chem.libretexts.org/LibreTexts/University_of_Denver/Chem_2132%3A_rememberingsomer.com_of_the_Elements/Unit_3%3A_Descriptive_rememberingsomer.com/09%3A_Building_a_Network_of_Ideas_to_Make_Sense_of_the_Periodic_Table/9.3%3A_The_Diagonal_Effect
In short, the diagonal relationships are based on two effects: the increasing efficient nuclear charge throughout a duration and the decreasing reliable nuclear charge down a group. Efficient nuclear charge increases across a duration because the number of shielding electrons in the inner shells is constant while over there are additional protons in the cell core of the atoms of the elements throughout the period. Reliable nuclear fee decreases down the group as there is an enhancement shell the shielding electrons from one facet to the following in the group. (These are comparable to the fads in metallic character stated in Pritt Balagopal"s answer.)
These two contending effects release each various other out and thus, chemists believe that the chemical properties of aspects in a diagonal should be similar.
