Question

1. which model of the atom described the atom like a solar system in which the electrons orbited around the nucleus?

thomson
quantum mechanical
bohr
dalton

Explanation:

• Thomson's model is the "plum - pudding" model where electrons are embedded in a positively charged "soup".
• The quantum - mechanical model describes electrons in terms of probability clouds (orbitals) rather than fixed orbits.
• Dalton's model is the "billiard ball" model where atoms are indivisible and have no internal structure like electrons orbiting.
• Bohr's model has electrons orbiting the nucleus in fixed, circular paths similar to planets orbiting the sun (solar - system like).

Answer:

C. Bohr
