Match the atomic model feature with its corresponding model:
Electrons orbit randomly ↔️ Rutherford Model
Electrons orbit in fixed energy levels ↔️ Bohr Model
Rutherford's Nuclear Model proposed that the atom has a dense, positively charged nucleus.
True
Steps involved in electron transitions in Bohr's Model
1️⃣ Electron absorbs photon
2️⃣ Electron jumps to higher energy level
3️⃣ Electron emits photon
4️⃣ Electron returns to lower energy level
The Thomson's Plum Pudding Model suggested the atom was a sphere of positive charge with electrons scattered throughout, in contrast to the later Rutherford model.dense
The Rutherford's Nuclear Model proposes that electrons orbit the nucleus in various energy levels, similar to planets orbiting a star.nucleus
In Bohr's Model, electrons can only occupy discrete energy levels, with each level corresponding to a fixed amount of energy.charge
The Bohr Model can explain the emission of discrete spectral lines, unlike the Rutherford Model.
True
Electrons in an atom orbit the nucleus in specific energy levels.
