Question

1. The H atom and the Be +3 ion each have one electron. Does the Bohr model predict their spectra accurately? Would you expect their line spectra to be identical? Explain,

Answer 1

Answer:

yes the Bohr model predicts their spectra accurately

Explanation:

The Bohr model based on one electron system

The atom H  has a single atom and the ion Be+3 has a single atom as well and this proves that the Bohr model predicts their spectra accurately .

also apply the equation model to further explain

E = $\frac{-(z^2) (2.18 * 10^{-18}j) }{n^2}$

z = atomic number

for H the value of z = 1

for Be+3 the value of z = 4

when this values are substituted into the equation above

E =  $\frac{-(1) (2.18 * 10^{-18}j) }{n^2}$ ,   E = $\frac{-(4) (2.18 * 10^{-18}j) }{n^2}$

this results show that the energy  level of Be+3 is higher than the energy level of H by a factor of 16 , and this shows that their line patterns are similar
