Question 24
Table 4.2 shows six historical models: Dalton (1803), tiny indivisible balls; Thomson (1904), negative electrons embedded in positive material (called proton “soup” in the book); Rutherford (1911), a small heavy nucleus with electrons moving around it; Bohr (1913), electrons in shells; Schrödinger (1926), an electron cloud around the nucleus; Chadwick (1932), neutral neutrons as well as positive protons in the nucleus. These are simplified models, not exact pictures.
Do you think the most important parts are shown in the model? (Remember that these models are simplified representations of real life.)
