Ionization energy, an Uncommon card
In physics and chemistry, ionization energy, or ionisation energy is the minimum energy required to remove the most loosely bound electron of an isolated gaseous atom, positive ion, or molecule.

Power 143 (ATK + DEF): stronger than 70 % of WikiCards cards.
The facts on the card
The card carries these facts from its Wikipedia article.
- The first ionization energy is quantitatively expressed as X + energy ⟶ X+ + e− where X is any atom or molecule, X+ is the resultant ion when the original atom was stripped of a single electron, and e− is the removed electron.
- Ionization energy is positive for neutral atoms, meaning that the ionization is an endothermic process.
- Roughly speaking, the closer the outermost electrons are to the nucleus of the atom, the higher the atom's ionization energy.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ionization energy article was read about 59,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 77 and blocks with 66: each hit it takes is cut by 26 %.
How to get Ionization energy
Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
