4.5 quantization and quantum numbers\nwhich of the following orbitals is largest in size?\no 3d\no 4d\no 2p\no 3p
Answer
Explanation:
Step1: Understand orbital size trend
Orbital size increases with the principal quantum number (n). For orbitals with the same angular - momentum quantum number (l), the one with a higher n is larger. Also, for a given n, the size increases with l (s < p < d < f).
Step2: Analyze each option
- For 3d: n = 3, l = 2.
- For 4d: n = 4, l = 2.
- For 2p: n = 2, l = 1.
- For 3p: n = 3, l = 1. Since 4d has the highest principal quantum number among the given options, it is the largest.
Answer:
4d
