WebTrends in physical properties occur across all Periods in the Periodic Table. This question is about trends in the Period 2 elements from lithium to nitrogen. (a) €€€€Identify, from the Period 2 elements lithium to nitrogen, the element that has the largest atomic radius. WebThere are many exceptions to the trend. Careful examination will show that there is a sudden drop in ionization energy for members of the Boron Group (Group 13) compared to the previous element. That is because Group 13 is where the elements switch from filling s or back-filling d orbitals to filling p orbitals.
