How many decimal places does ether have, i.e. how many wei make one ETH expressed as a power of ten?

Answer

0 ETH

18 uint256, 18 decimals

answer
the exponent, as a whole number (one ETH is 10 to this power wei)
source
Answer from a reputable public source you actually read (the Bitcoin or Ethereum documentation, the EIP repository, chainlist.org, or a major reference) 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 blockchain technology. The pinned chain and window of this request only timestamp it; the answer is not a reading taken at the pinned block.
