What was the attempt of the Thomson model in atomic theory?
What was the attempt of the Thomson model in atomic theory?
- To prove that atoms are composed entirely of electrons
- To disprove the existence of positively charged particles in atoms
- To reconcile the discovery of the electron with the knowledge that atoms had a net charge of zero (correct)
- To reconcile the discovery of the electron with the knowledge that atoms had a net charge of one
What did the Rutherford model conclude about the distribution of positive charges in an atom?
What did the Rutherford model conclude about the distribution of positive charges in an atom?
- They are located in the nucleus only
- They are concentrated in a small region of space (correct)
- They are absent in the atom
- They are uniformly distributed throughout the atom
How did the Bohr model build upon the Rutherford model's description of the atom?
How did the Bohr model build upon the Rutherford model's description of the atom?
- By proposing that there are multiple nuclei in an atom
- By denying the existence of electrons
- By claiming that electrons occupy fixed positions in the nucleus
- By introducing the concept of orbiting electrons around a positively charged nucleus (correct)
