The metallic character decrease from left to right.
I'm not quite sure, but the further right you go on the periodic table the less metalic it gets.
A periodic table displays all known elements arranged by their atomic number, electron configuration, and recurring chemical properties. It provides valuable information such as element names, symbols, atomic masses, and group/family classifications. Additionally, the table helps scientists predict the behavior and properties of elements based on their position.
The most stable atom in the periodic table is helium.
