ANS. The third period of the periodic table includes the elements Na,Mg,Al,Si,P,S,Cl,Ar and the fouth period includes the elements K,Ca,Sc,Ti,V,Cr,Mn,Fe,Co,Ni,Cu,Zn,Ga,Ge,As,Se,Br,Kr.
The coloured elements show the transition elements here.The transition elements are those elements who have a patially filled d sub shell or whose cations give rise to partially filled d subshell.
The electronic configuration of five elements from these is as given below:
Na[11] : 1s22s22p63s1
Ar[18]:1s22s22p63s23p6
Ca[20]:1s22s22p63s23p64s2
Co[27]:1s22s22p63s23p63d74s2
Zn[30]:1s22s22p63s23p63d104s2
