the H atom and 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

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

It must be measured in k.hope my answer is to you : )

Zinc contains about 30 protons
