Question:
Which atomic model states that it is impossible to know the exact location of electrons around the nucleus?
A) Bohr model
B) Dalton model
C) Plum pudding model
D) Electron-cloud model
Expert Verified Solution:
The Correct Answer: D) Electron-cloud model
Description: The Electron-cloud model, also known as the Quantum Mechanical model, posits that it is impossible to precisely determine the exact location of electrons around the nucleus at any given moment. Instead, this model describes electrons as existing in regions of probability, or “clouds,” where they are likely to be found. This model contrasts with earlier atomic models such as the Bohr model, which depicted electrons in fixed orbits around the nucleus, or the Plum pudding model, which described electrons embedded within a positively charged “pudding.
