They radiate energy when at rest in discrete orbits

They do not radiate energy while revolving in discrete orbits (correct)

They continuously radiate energy while revolving in discrete orbits

They radiate energy only when jumping between orbits

How are the orbits of electrons arranged according to Bohr's model?

In a random pattern around the nucleus

In a linear pattern around the nucleus

Concentrically around the nucleus (correct)

In an expanding spiral around the nucleus

What is the behavior of electrons in Bohr's model when jumping between energy shells?

They absorb energy continuously

They absorb or emit a definite amount of energy (correct)

They emit energy continuously

They do not change energy levels

Why did Rutherford's model fail to explain the stability of atoms?

Study Notes

Bohr's Model of the Atom

Electrons occupy specific energy levels (discrete orbits) around the nucleus, jumping from one energy level to another by emitting or absorbing energy.
Orbits are arranged in a series of concentric circles (shells) around the nucleus, with each shell having a specific energy level.

Electron Behavior in Bohr's Model

When jumping between energy shells, electrons emit or absorb energy in the form of photons.
Electron transitions between energy shells are accompanied by the emission or absorption of energy.

Limitations of Rutherford's Model

Rutherford's model failed to explain the stability of atoms because it did not account for the energy levels of electrons.

Bohr's Proposal on Electron Orbits

Electrons revolve in specific, stable orbits (energy levels) around the nucleus, rather than collapsing into the nucleus due to electrostatic attraction.
