The 37 transitional elements include a huge number of elements that humans use, even require, on a daily basis. The Transitional Elements explores the discovery, uses, classification, and compounds, and the impact of these elements on the individual reader.
TRANSITION ELEMENTS - welcome to the exciting world of dubnium, hassium, yttrium, ytterbium, darmstadtium, technetium, meitnerium, rutherfordium, seaborgium, dysprosium, praseodymium, protactinium, and oh-so-many-more elements I have NEVER heard of…or as they're more prosaically known, "metals."*
Interesting if confusing stuff - but then I'm in my 60's; maybe a present day 10-year-old would process this better. At least I now understand what "valence" electrons are, and the difference between molecules, compounds and alloys (see Mendeleyev review). Also, I continue to love the fact that every element heavier than iron has to be forged in an exploding supernova; plus the equally mind-blowing fact that if an atom of hydrogen were the size of the Super Dome, its nucleus would be the size of a pea - cool!
* Obviously excluding the 12 alkali and alkaline Earth metals. I mean, obviously.
