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

A

Larger the value of n , the larger is the orbit radius

B

Equation can be used to Calculate the change in energy when the electron changes orbit

C

For n=1 , the electron has a more negative energy than it does for n=6 which means that the electron is more loosely bound in the smallest allowed orbit

D

The negative sign in equation simpty means that the energy of electron bound to the nucleus is lower than it would be if the electrons were at the infinite distance from the nucleus
