Question

The Figure below shows the different atomic models that eventually led to the modern atomic theory. Which of the following is true about Models A-E? Multi slect-2









a
Both A and C contain electrons in specific orbits
b
In B is the Quantum mechanical model where electrons are described as both waves and particles
c
E represents Dalton and Democritus model that states atoms are solid and indivisible
d
All these models contain negatively charged electrons which are particles
e
D was the atomic model proposed by Neils Bohr

Answer 1

Correct answers: d and e.

- e: Model D is the Bohr model (electrons in quantized circular orbits around a small nucleus).
- d: All the pictured models show negatively charged electrons (even the modern/quantum model treats electrons as having negative charge; quantum theory describes wave–particle behavior but the electron still carries negative charge).
