30. The Bohr's energy equation for H atom reveals that the energy level of a
shell is given by E= -13.58/n^2eV. The smallest amount that an H atom will
absorb if in ground state is:
1) 1.0 eV
2) 3.39 eV
3) 6.79 eV
4) 10.2 eV
Answers
answer : option (4) 10.2 eV
it has given that the Bohr's energy equation for H - atom reveals that energy level of a shell is given by, E = -13.58/n² eV.
we have to find the smallest amount of energy that an H-atom will absorb if in ground state.
actually, the smallest amount of energy that an H-atom will absorb if in ground state = energy difference between first and 2nd energy levels.
energy of electron in first energy level, E₁ = -13.58/1² eV
= -13.58 eV
energy of electron in 2nd energy level, E₂ = -13.58/2² eV
= -13.58/4 = 3.395 eV
now energy difference between first and second energy levels = E₂ - E₁
= -3.395 - (-13.58)
= 10.185 eV ≈ 10.2 eV
therefore, the smallest amount of energy that an H-atom will absorb if in ground state is 10.2 eV.
