s block elements chemistry

Using periodic table (xerox copy of periodic table may be provided to students) and by discussion students may write the electronic configuration and defines s-block element They may cite more examples. As a group work they may be asked to compare first ..

According to the electronic configurations;of elements; four blocks-are envisaged in the periodic table. If the differentiating electron of an element enters s subshell, it is placed in s block. Similarly the other three p, d an..

Elements having' its and ns electron cosfieuration in their outermost atomic orbital are known as .v block elements. Alkali metal elements of I A group and alkaline earth elements of II A group are present in s-block..

1. The elements that lie in between s-block and p-block are called as the d-block elements. 2. The transition metals are studied in 4 horizontal series corresponding to filling of the sublevels of 3d (Sc to Zn), 4d (Y to Cd), 5d (La to Hg, ..
