The trends shown in the given figure reflect the tendency of ___ A_elements to form ions that will have an identical electron configuration to that of a noble gas. The elements of groups 1A,2A, and 3A shown in the figure ___ B_electrons to form C-charged ions. The elements of groups 5A,6A, and 7A normally ___ \( \mathrm{D}_{\text {_-_ }} \) electrons to form ___ \( \mathrm{E}_{\text {__- charged ions. The }} \). The series represents the filling of core orbitals, and the number of electrons is mostly constant. Examine the figure below, which shows the elements that form predictable ions
