Topic 2 - Inorganic chemistry Exam With 100% Correct Answers 2024 What is the trend in atomic radius down group 7 Increases because as you go down the group, there are more shells so more shielding so a weaker attraction between the nucleus and the outer electrons is the ionic radius bigger compared to the atomic radius in group 7 Yes because the halide ion has the same number of protons but more electrons than the halogen atom so the attraction is weaker What is the trend in boiling poi...
