Mr Bale, I'm absolutely begging you: don't stop making these videos. Please cover all of the A-level syllabus; I can't tell you how thankful I am for these videos.
What a thumbnail! Great video as always but I would have liked to seen some of the key terms that you said (e.g. diprotic acid) written on screen for reference (like what you did for electron shielding and atomic radius). Hope your doing well :)
