Question
Part B The probability of finding an electron at a point in an atom is referred to as the probablity density(The spatial distribution of these densities can be derived from the radial wave function R(r) and angular wave function Y(0,), then solving the Schrödinger equation for a specific set of quantum numbers. Which of the following statements about nodes and probability density are accurate? Select all that apply The 3p orbitals have two nodes. The 4f orbitals have three nodes. The 2s orbital does not have any nodes. The probability of finding an electron at the center of a p orbital is zero. O The probablity of finding an electron at the center of a d orbital is greater than zero. Submit My Answers Give UpExplanation / Answer
1,2,4 statements are correct.
No. Of nodes =n-1 for a given orbital (n-principal quantum number)
Hence for 3p orbital =n-1=3-1=2 nodes
4f orbital =4-1=3nodes
2s orbital=2-1=1 node but given is zero(wrong)
Probability of finding the electron at the center of p-orbitals which is nothing but the nucleous is zero
For d-orbitals at the center is also zero probability of finding the electron, it cant be greater than zero
