Based on equation $E = -2.178 \times 10^{-18} \ J \ \frac{Z^2}{n^2}$,certain conclusions are written. Which of them is not correct?

  • A
    For $n = 1$,the electron has a more negative energy than it does for $n = 6$,which means that the electron is more tightly bound in the smallest allowed orbit.
  • B
    The negative sign in the equation simply means that the energy of the electron bound to the nucleus is lower than it would be if the electron were at an infinite distance from the nucleus.
  • C
    Larger the value of $n$,the larger is the orbit radius.
  • D
    The equation can be used to calculate the change in energy when the electron changes its orbit.
