6. Within the halogens (Main Group VII elements) does the distance of the valence energy level from the nucleus increase or decrease as the atomic number increases? (Circle one) 7. Since nonmetals tend to gain electrons, would the trend you described in question 6 cause the reactivity of the nonmetals within this group to increase or decrease as atomic number increases? (Circle one) 8. Was your observed order of reactivities consistent with your prediction in question 7 ? 9. In terms of electronic structure, why do elements in the same group display similar chemical properties?
