Question : 32 of 54

Marks: +1, -0

Which of the following option is/are correct?

Atomic orbitals are completely described as the regions where the probability of finding the electron is maximum.
The weighted average of large number of observations for measuring the radius of 1s orbital is greater than 52.9pm(r2R2 dr represents the total probability of finding the electron between r and r+dr).
The energy of 4s is always lower than 3d for multi electronic atom/ ion.
Energy needed to excite an electron from n=2 to n=4 state is ‌
25
28
times the energy needed to excite an electron from n=2 to n=5 for a single electron atom ∕ ion.
