art A:  How does ionization energy change down a group?   increases from left to right   decreases from left to right   increases from top to bottom   decreases from top to bottom Part B:  Why is Ionization energy smaller for larger atoms?    Sheilding. The nucleus cannot hold onto the electrons as well and loses them easier   Shielding. The nucleus holds onto the electrons stronger and does not lose them easily   There is no explanation Part C:  According to the trend, which of these 4 elements has the largest ionization energy?   Be (atomic# 4)   Sr (atomic# 38)   F (atomic# 9)   I (atomic# 53) Part D:  According to the trend, which of these 4 elements has the smallest ionization energy?   Be (atomic# 4)   Sr (atomic# 38)   F (atomic# 9)   I (atomic# 53
