Based on equation `E=-2.178xx10^(-18)((z^(2))/(n^(2)))J`, certain conclusions are written, which of them is not correct-

A

equation can be used to calculate the change in energy when the electron changes orbit

B

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

C

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

D

larger the value of n, larger is the orbit radius

Text Solution

Verified by Experts

The correct Answer is:
B
Since the electron is more lightly bounded in the smallest allowed orbit.
