1.	Hello Dears! Question : Explain the trends of Valency, atomic size and metallic and non-metalic character of element Present in Modern Periodic Table. #Cool Moderator!
Answer» EXY of am elelment is determined by the no. of electorlns presebt in the outermost shell of its atom is called valency trends2atomic size-the size of the atom is indicated by its radius. atomic radius is the distance between the NUCLEUS of the atom and its outermost shell .3 it is seen taht the metallic ELEMENTS like na, mg, are toward left .the non metallic element such as sulphur chlorine at words right .the metallic element Silicon lies in between these two types of similar pattern is also observed in the other PERIODS .
