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...

Atomic Radius, Nuclear Charge, Electron Shielding - What are the 3 things that affect first ionisation energy? Increase. More protons- stronger attraction. Not much extra shielding. - What is the general trend in ionisation energy across periods? And why? Decrease due to increased attraction between electrons and nucleus. - What is the trend in atomic radius across a period? Increase due to metallic bonds getting stronger. - What is the trend in boiling points across metals? Silicon. Stro...

BTEC APPLIED SCIENCE LAB REPORT ON OXIDATION AND REDUCTION. FND04: FURTHER CHEMISTRY FOR BIOSCIENCES - LAB REPORT Oxidation and Reduction (REDOX) Reactions Introduction Oxidation-reduction reactions, otherwise known as redox reactions, are fundamentally a process that involves a transfer of electrons. Oxidation can be defined as loss of electrons and reduction as gain of electrons. Therefore, oxidation results in an increase in oxidation number and reduction a decrease in oxidation numb...
