AP Chemistry
1.5 Atomic Structure and Electron Configuration
A student investigates electron shielding and the shell model of the atom by comparing the relative populations of inner-shell and outer-shell electrons for main-group elements. Based on the ground-state electron configuration of a neutral bromine atom (
\(\text{Br}\), \(Z = 35\)), what is the ratio of the number of core electrons to the number of valence electrons?
\(\text{Br}\), \(Z = 35\)), what is the ratio of the number of core electrons to the number of valence electrons?
