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...

TOF steps - CORRECT ANSWER-1) ionisation 2) acceleration 3) ion drift 4) detection 5) analysis Electron impact - CORRECT ANSWER-Sample vaporised and electron gun fires high energy electrons at it which knock off 1 electron from each particle, making them 1+ ions NB- can knock off more than one e or break molecular ion electrospray ionization - CORRECT ANSWER-Sample dissolved in volatile solvent then injected through needle to give fine mist which is attached to positive end of high v...

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...
