Question

natalie observes these characteristics in the model of an atom. (i) includes positive charge (ii) contains electrons (iii) explains the photoelectric effect (iv) suggests the probable location of electrons which model is natalie most likely examining? bohr model daltons model plum pudding model electron - cloud model

Explanation:

1. Bohr model: Has a positively - charged nucleus, electrons in fixed orbits, but doesn't fully explain the photoelectric effect and electron probabilities well.
2. Dalton's model: Atoms are indivisible and don't have sub - atomic particles like electrons in the way described, so it's not relevant.
3. Plum pudding model: Has positive charge and electrons, but doesn't explain the photoelectric effect or electron probabilities accurately.
4. Electron - cloud model: Has a positively - charged nucleus, contains electrons, can explain the photoelectric effect using quantum theory, and suggests the probable location of electrons in electron clouds.

Answer:

electron - cloud model
