Consider the following statements

$\left|{\Psi }^2\right|$is a measure of electron density at a point in an atom

Radial probability function  $(=4\pi r^2{R}^2{\Psi }^2)$gives the probability of finding the electron at a distance r (atomic radius) from the nucleus regardless of direction

III. The shape of an orbitals is defined as a surface of constant probability density that encloses some large fractions of the probability of finding the electron.

Select the correct statements.

 

I.$\left|{\Psi }^2\right|$ is a measure of electron density at a point in an atom. Thus, the statements is correct.

II. Radial probability function $4{\pi }^2{R}^2{\Psi }^2$ gives the probability of finding the electron at a distance t from the nucleus regardless of direction. Thus, the statement is correct.

III. The shape of an orbitals is defined as a surface of constant probability density that encloses some large fraction of the probability of finding the electron. Thus, the statement is correct.
