Select the correct statement

Options

A. Lower value of quantum number l indicates that there is a higher probability of finding the 3s electron close to the nucleus than those of 3p and 3d electrons
B. energy of 3s orbital is less than for the 3p and 3d orbitals
C. At the node, the value of the radial function changes sign
D. The radial function depends upon the quantum numbers n and l

Answer

A, B, C, D

Explanation

All are facts
Energy order `rarr3s lt 3p lt 3d lt 3f," 3s is closer to nucleus "therefore" is most stable."`
Whereas 3f is farthest from nucleus and hence has maximum energy and is least stable.
