The facts on the card
The card carries these facts from its Wikipedia article.
- As a free radical, it is highly reactive and consequently short-lived, making it a pivotal species in radical chemistry.
- In nature, hydroxyl radicals are most notably produced from the decomposition of hydroperoxides or, in atmospheric chemistry, by the reaction of excited atomic oxygen with water.
- They are also significant in radiation chemistry, where their formation can lead to hydrogen peroxide and oxygen, which in turn can accelerate corrosion and stress corrosion cracking in environments such as nuclear reactor coolant systems.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Hydroxyl radical article was read about 34,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 72 and blocks with 62: each hit it takes is cut by 25 %.
