Group electronic configurations

Molecule group Electron configurations Resulting states... 

E9.3 These elements are Group 15. This group is very diverse. N and P arc nonmetals As and Sb arc metalloids, and Bi is metallic. The +5 and +3 oxidation states are common for the group electron configuration of ns p. Phoshine and arsine are well-known toxic gases. 

Group electron configuration is ns . All members have the + 1 oxidation state and form an E ion. Atoms have the largest size and lowest IE and EN in their periods. Down the group, atomic and ionic size increase, while IE and EN decrease. 

Group electron configuration is ns np. Down the group, the number of oxidation states decreases, and the lower (+2) state becomes more common. Down the group, size increases. Because transition and inner transition elements intervene, IE and EN do not decrease smoothly. 

Group electron configuration is ns nt . The np sublevel is half-filled, with each p orbital containing one electron. The number of oxidation states decreases down the group, and the lower ( + 3) state becomes more common. Atomic properties follow generally expected trends. The large ( 50%) increase in size from N to P correlates with the much lower IE and EN of P. 

Group electron configuration is ns np -, elements lack one electron to complete their outer level. The — 1 oxidation state is the most common for all members. 

Group electron configuration is ns np. As in Groups 3A(13) and 5A(15), a lower (+4) oxidation state becomes more common down the group. Down the group, atomic and ionic sizes increase, and IE and EN decrease. 

Group electron configuration is Is for He and ns np for the others. The valence shell is filled. Only Kr, Xe, and Rn are known to form compounds. The more reactive Xe exhibits all even oxidation states (-I-2 to -I-8). This group contains the smallest atoms with the highest lEs in their periods. Down the group, atomic size increases and IE decreases steadily. (EN values are given only for Kr and Xe.)...
