The number of radial node/s for \({\mathrm{3 p}}\) orbital is / are
1 3
2 2
3 1
4 4
Explanation:
No. of radial nodes \( = {\rm{n}} - l - 1\) For ' 3 p ' orbital, \({\rm{n = 3}},l{\rm{ = 1}}\) \({\mathrm{\therefore}}\) No. of radial nodes \({\mathrm{=3-1-1=1}}\) So, the correct option is (3).

Assertion : Shapes of the orbitals are represented by boundary surface diagrams of constant probability density. Reason : Boundary surface diagram helps in interpreting and visualizing an atomic orbital.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
The boundary surface diagram corresponds to a constant probability density of \({\psi ^{\text{2}}}\). This diagram illustrates the shape of the orbital, which encloses a region or volume where the probability of finding the electron is notably high, typically around \(90 \%\). So option (1) is correct.

Each orbital has a nodal plane. Which of the following statements about nodal planes are not true?
1 A plane on which there is zero probability that the electron will be found.
2 A plane on which there is maximum probability that the electron will be found.
3 Both (1) and (2)
4 None of the above
Explanation:
A plane on which there is zero probability that the electron will be found is known as nodal plane.
