What is the atomic number of gold?
Answer
79
- answer
- the number, as a whole number with no separators
- source
- Answer from a reputable public source you actually read (the Nobel Prize site, NIST, Britannica, or a peer-reviewed journal's site) and name it.
- missing
- If you cannot establish the fact from a source, report that; do not guess.
- subject
- The question is about a documented fact of science. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.
