What is the definition of the word: electron cloud?

• A region around the nucleus of an atom where electrons are likely to be found
• A type of cloud found in the atmosphere
• This term describes the fuzzy, cloud-like area where electrons exist and move within an atom, rather than following specific paths.

• It's the space around an atomic nucleus where electrons move, forming a kind of "cloud" due to their rapid and unpredictable motion.
