how long does it take an atom to travel from the nucleus to the end of the visible tail?
how long does it take an atom to travel from the nucleus to the end of the visible tail?
I am refering to Bohr’s theroem of hydrogen. He used a formula involving the “Rydberg constant”. My question is why are energy levels assigned negative values is it because the negative sign says that the energy is giving off to the surroundings? or is it because the negative sign signifying that the energy of the electron in the atom is lower than the energy of a free electron? Thanks for helping

Q.) In a future hydrogen-fuel economy, the cheapest source of H2 will certainly be water. it takes 467kJ to produce 1 mol of H atoms from water. what is the frequency, wavelength, and minimum energy of a photon that can free an H atom from water?
V=E/h–>> { (467kJ)(10^3J/1KJ) (mol/6.022×10^23) / (6.626×10^-34) }
E=7.75×10^-19
V=1.17×10^15
Lamda=hc/E–>> { (6.626×10^-34J) (3.00×10^8) / (7.75×10^-19) }
Lamda=2.56×10^-7
So is this right?
