With the determination of the bound electronic configuration of Sc as 3 d4 s 24 p, the order of filling of electron shells of the first transition series negative ions is found to be 4 s 24 p, 3 d4 s 24 p, followed by 3 d k4 s 2 ( k = 3,4,…, 10)....
Explain briefly about the groups of the modern periodic tabele and also classify the elements depending on electron filling in s-, p-, d- and f-subshells along with the position in the periodic table. View Solution The order of screeing effect of electrons of s,p,d and f orbitals ...
This result was predicted by Flory38 by considering space-filling arguments and the fact that the interaction of segments of different chains is equal and therefore screened out.

These pillars are pat- terned on a square grid with a pitch (P) that is 500 nm larger than the pillar length (i.e., P = L + 500 nm) to reduce coupling between neighboring pillars while maintaining a high filling fraction. Figure 1a,b show oblique and top-...
It is important to note that periodicity is derived from the measurement of long-range order–disorder, which is explained as the periodic filling of space by atoms, in most cases by using atoms with spherical shapes. In contrast, “glassy” materials are generally described as amorphous solids...
