12.1 The size of the atom in Thomson's model is no different from the atomic size in Rutherford's model.

In the ground state of Thomson's model, electrons are in stable equilibrium. While in Rutherford's model, electrons always experience a net force.

A classical atom based on Rutherford's model, is d

$| Δ E_{0} | = (- 136 {1 - \frac{1}{4}}) e V$

|DE₀| = –10.2

$λ = \frac{12400}{10.2} \times 1 0^{- 10} m$

$ρ = \frac{h}{λ} = \frac{6.63 \times 1 0^{- 34} \times 10.2}{12400 \times 1 0^{- 10}}$

$?$ $m v = \frac{h}{λ}$

$1.8 \times 1 0^{- 27}$

$v = \frac{6.63 \times 10.2 \times 1 0^{- 34}}{12400 \times 1 0^{- 10}}$

$v = \frac{6.63 \times 10.2}{12400 \times 1.8} \times 1 0^{3}$
