Answer
1p, 3f, 2d
Work Step by Step
To determine which orbital designations are incorrect, we need to apply the rule that the azimuthal quantum number
𝑙 must be less than the principal quantum number 𝑛:
𝑙=0 → s orbital
𝑙=1 → p orbital
𝑙=2 → d orbital
𝑙=3 → f orbital
Let's analyze the given orbitals:
1s: 𝑛=1,𝑙=0, 𝑙
