The facts on the card
The card carries these facts from its Wikipedia article.
- It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals.
- Pure radium is silvery-white, but it readily reacts with nitrogen upon exposure to air, forming a black surface layer of radium nitride.
- All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1,600 years.
Why it is Rare
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Radium article was read about 270,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 83 and blocks with 96: each hit it takes is cut by 38 %.
