Options
- A(a) - (s), (b) - (p), (c) - (q), (d) - (r)
- B(a) - (p), (b) - (r), (c) - (s), (d) - (q)
- C(a) - (q), (b) - (p), (c) - (s), (d) - (r)
- D(a) - (p), (b) - (q), (c) - (r), (d) - (s)
Correct answer
D. (a) - (p), (b) - (q), (c) - (r), (d) - (s)
Step-by-step solution
- (a) The orbital wave function for an electron in an atom has - (p) no physical meaning: The wave function itself does not have physical meaning, but the square of the wave function gives the probability density. - (b) Total number of nodes - (q) (n 1): The total number of nodes (radial and angular) for an orbital is equal to (n-1 ), where (n ) is the principal quantum number. - (c) For 1s orbital, probability density is - (r) maximum near the nucleus and decreases sharply as we move away from it: The probability
