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,

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 =

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 =   ,   E =

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
