Question

the ionization of hydrogen atom is 1.312×10^6 J mol^-1 . The energy required to excite electron from n=1 to n=2 is?​

Answer 1

The ionisation enthalpy of hydrogen atom is 1.312×106J⋅mol-1. The energy required to excited the electron in theatom from n=1 to n=2 is- =9.84×105Jmol-1.

Answer 2

I'm Giving You 2Answers You Can Write Any One Of Them Both Are Correct.

You Can Write As The Above Image Given Or As The Answer Given Below :-

Energy of electron in first orbit =E1=−1312 kJ/mol

Energy of electron in first orbit =E1=−1312 kJ/molEnergy of electron in secondorbit =E2=−221312=−328 kJ/mol

Energy of electron in first orbit =E1=−1312 kJ/molEnergy of electron in secondorbit =E2=−221312=−328 kJ/molHence, Energy required to excite a hydrogen electron from n=1 to n=2 =E2−E1=−328−(−1312)=984 kJ/mol
