What is the energy required to remove the electron from a hydrogen atom in the n = 11 state?
zaharov [31]

Based on the data given, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV

<h3>What is ionization energy?</h3>

Ionization energy is the energy requiredto remove an electron from a neutral atom or a cation in its gaseous state.

To calculate the energy required to remove the electron from a hydrogen atom in the n = 11 state, the formula below is used:

  • E_n = \frac{E_0 × Z^{2}}{n^{2}}

where

E_0  \: is  \: ground  \: state  \: energy  \: of \:  hydrogen \:  atom \:  = -13.6 eV \\

  • Z = 1
  • n = 11

substituting the values:

E_n = \frac{ - 13.6 × 1^{2}}{11^{2}} \:  =  - 0.112 \: eV

Therefore, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV

What is the net force acting on the box
Darya [45]

Answer:

According to Mr. Newton, an object will only accelerate if there is “net force” acting upon it. A net force is the sum of all forces acting on an object. A net force is capable of accelerating a mass.
