Electron diffraction quiz: 3 questions
Three questions on the Electron diffraction card, the way WikiCards duels ask them. Pick an answer, the facts are just below.
Find the missing word
It occurs due to elastic scattering, when there is no change in the energy of the ______.
Answer
electrons. It occurs due to elastic scattering, when there is no change in the energy of the electrons. From the Electron diffraction article on Wikipedia.
Which of these Wikipedia articles is read the most in a year?
Answer
CRISPR gene editing. CRISPR gene editing 140,000 · List of interstellar and circumstellar molecules 68,000 · Galileo project 33,000 · Electron diffraction 20,000 Wikipedia reads over a year.
In a duel, each round asks a question like these about the opposing card, with 15 seconds to answer.
The facts on the card
The card carries these facts from its Wikipedia article.
- It occurs due to elastic scattering, when there is no change in the energy of the electrons.
- The negatively charged electrons are scattered due to Coulomb forces when they interact with both the positively charged atomic core and the negatively charged electrons around the atoms.
- The resulting map of the directions of the electrons far from the sample is called a diffraction pattern, see for instance Figure 1.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Electron diffraction article was read about 20,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 90 and blocks with 100: each hit it takes is cut by 40 %.
How to get Electron diffraction
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.
