Structure of Atom - Result Question 14

####14. The energy of second Bohr orbit of the hydrogen atom is 328kJmol1; hence the energy of fourth Bohr orbit would be:

[2005]

(a) 41kJmol1

(b) 82kJmol1

(c) 164kJmol1

(d) 1312kJmol1

Show Answer

Solution:

  1. (b) En=E1×(Zn)2

E2=E122=328kJ/mol

E4=E142

E4E2=2242=122

E4=E222=3284kJ/mol=82kj/mol
