Question

Using balmer series, calculate ionisation energy of hydrogen atom in KJ/mol.

Answer 1

multi multiply Planck's Constant by the speed of light and you're the reason why wavelength of the emissions multiplying planks constant which has a value of 6.626 into 10 to the power of minus 32 joules second the light speed of light with the value of 3.00 into 10 to the power of 8 metre per second is 1.988 into 10 to the power of minus 25 joule meter and divide this by wavelength which has a value of 9.11×10 to the power -8 which gives 2.182×10 to the power -18 joule this is the first ionization energy of hydrogen atom
