Based on equation E=-2.178 10⁻¹⁸ ~J ( Z^2 n^2 ) certain conclusions are written. Which of them is not correct?

Options

  1. AThe negative sign in equation simply means that the energy of electron bound to the nucleus is lower than it w
  2. BLarger the value of n , the larger is the orbit radius
  3. CEquation can be used to calculate the change in energy when the electron changes orbit
  4. DFor n=1 the electron has a more negative energy than it does for n=6 which means that the electron is more loo

Correct answer

D. For n=1 the electron has a more negative energy than it does for n=6 which means that the electron is more loo

Step-by-step solution

If n=1 , E₁=-2.178 10⁻¹⁸ Z^2 ~J If n=6 aligned E₆ & = -2.178 10⁻¹⁸ Z^2 36 ~J & =6.05 10⁻²⁰ Z^2 ~J aligned From the above calculation, it is abvious that electron has a more negative energy than it does for n=6 . It means that electron is more strongly bound in the smallest allowed orbit.
