Based on equation
E=-2.178 x 10^-18 J  certain conclusions are written. Which of them is not correct?

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

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

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