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

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

B

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

C

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

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
Statement (d) is not correct because in the smallest allowed orbit, the electron is more tightly bound and not loosely bound
