Question

Calculate the energy required to excite the hydrogen electron from level n = 2 to level

n = 3 , as per the quantum model of the hydrogen atom. Also calculate the wavelength

third excited state.

of light that must be absorbed by a hydrogen atom in its 2 ^ (nd) excited state to reach the third excited state​

Answer 1

Answer:

+2.55

Explanation:

The Energy required to excite an electron from n₁= 4 state, ΔE=

13.6( $\frac{1}{n_{1}^{2} }$ -$\frac{1}{n_{2} ^{2} }$)

∴ ΔE=13.6( $\frac{1}{2^{2} }$ - $\frac{1}{4^{2} }$) eV

Or   ΔE= +2.55  eV

As higher states have more energy than the lower states, thus energy is given to the atom to excite.
