Question

the atomic models after dalton’s time included ideas about the atomic structure. which atomic model that shows the atomic structure is missing from this set?
o niels bohr’s model
o schrödinger’s model
o rutherford’s model
o thomson’s model

Explanation:

1. Analyze the given atomic models: The first model (electron cloud) is Schrödinger's (quantum mechanical), the second (plum - pudding, positive sphere with electrons) is Thomson’s, the third (electrons in orbits around nucleus) is Bohr’s.
2. Recall Rutherford’s model: It has a small, dense, positively - charged nucleus with electrons orbiting around (but not in fixed orbits like Bohr, and not a plum - pudding or electron cloud). So Rutherford’s model is missing from the set.

Answer:

Rutherford’s model
