Hi! I'm Hydrogen, but you can call me H. I am the smallest element in the universe, but don't underestimate me. I was here FIRST, before all the other elements. (Literally, I've been around since the very beginning - before the planets, the stars and even your great-great-great gran.). Follow me as we explore a day in the life of a periodic table, and meet a cast of characters that might just explode any second. This laugh-out-loud guide to the periodic table takes a playful look at different groups of elements and their characteristics, from the Hot Heads (the explosive ones) to the Introverts (the unreactive ones) Packed with fascinating facts about real-life chemistry - such as, did you know the potassium in bananas makes them radioactive? (Don't worry, you'd need to eat about 10 million of them to get the same radiation as an X-ray.) Written by comedian and chemist Freya McGhee, with hilarious comic strip illustrations by Aaron Blecha, this is the perfect funny read to teach kids aged 9+ about science without them even noticing.
