Question

kample 5: What is the energy required to remove an electron from second orbit of hydrogen atom?​

Answer 1

For Hydrogen’s second orbit, Z=1 and n=2So 5.45×10^-19 J is required to eject the electron from Hydrogen.P.S; The (-) in the equation is just for show, don't insert it in the calculatorP.S again;The energy of an electron can be calculated also bySo..13.6/2^2

=3.4eV
