Part B: Arrange the elements in decreasing order of the number
of valence electrons. Rank from most to least number of valence
electrons. To rank items as equivalent, overlap them.
Part C: Number the rows within each block of the periodic table
according to the shell for the highest-energy electrons in an atom
of those elements.
Drag the appropriate labels to
their respective targets.

Valence electrons: the number of electrons present in outermost shell of an orbital is known as valence electrons. the number of electrons is equal to the number. Group IA elements (H, Li, Na, K, Rb, Cs, Fr) contains one valence electron. Group IIA elementof (Be, Mg, Ca, Sr, Ba, Ra)contain two valence electrons. Group IIIA elements(B, Al, Ga, In, Tl) contain three valence electrons. Group IV A elements(C, Si, Ge, Sn, Pb)contain four valence electrons. Group V A elements(N, P, As, Sb, Bi)contain five valence electrons Group VI A elements(O, S, Se, Te, Po)contain six valence electrons. Group VII A elements (F, Cl, Br, I, At) contain seven valence electrons. group VIII A elements (he, Ne, Ar, Kr, Xe, Rn)contains eight valence electrons thus, the order of the elements from most valence electrons to least valence electrons is as follows: Kr = Ar > Br = Cl = Fr > O > As = Sb > Si > Al >
