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...

I achieved a high A* Grade in my final A-Level exams using these notes!!! I believe you can achieve an A* if you can memorise these notes! Simply use blurting, a method of active recall, to write everything you remember from the notes, then identify the parts you couldn’t remember, then repeat until you can remember it all! If you can do that, you’ve got an A* in the bag! They are clear, concise, and are laid out according to the specification; there is no information missing or in excess...

Biochem - 1st Year All amino acids contain a central carbon, a side chain (R group), an amino group and a __________ group. - correct answer Carboxyl Amino acids can undergo a proton transfer, thus giving both a (+) and (-) charge. This molecular state is called the ________. - correct answer Zwitterion Amino acid that are unable to be synthesised from biochemical pathways within a cell have to be consumed through dietary intake. These are called _______ amino acids. - correct ans...
