1. Electron Configuration:

* Zinc (Zn) has an atomic number of 30, meaning it has 30 electrons.

* Its electron configuration is: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰

2. Identifying Orbitals:

* s orbitals: There are 4 's' orbitals (1s, 2s, 3s, 4s)

* p orbitals: There are 3 'p' orbitals in each shell (2p, 3p). So there are 6 'p' orbitals.

* d orbitals: There are 5 'd' orbitals in each shell (3d).

3. Total Orbitals:

* 4 s orbitals + 6 p orbitals + 5 d orbitals = 15 orbitals

Therefore, zinc has a total of 15 orbitals.
