### Question on Electron Configuration

**Question:**

What element does the electron configuration \([Kr] \, 5s^2 \, 4d^{10} \, 5p^1\) correspond to?

- [ ] Kr
- [ ] In
- [ ] Cd
- [ ] Sn
- [ ] Sb

**Explanation:**

This is a question meant to test your understanding of electron configurations and how they relate to specific elements on the periodic table. The notation \([Kr]\) indicates that the electron configuration of Krypton is being used as a base, and the subsequent numbers denote the additional electrons that differentiate the element in question.

**Comparison of Orbital Energies in Hydrogen and Potassium Atoms**

The question posed is to compare the energies of the 3p and 3d orbitals in hydrogen (H) and potassium (K) atoms. You are required to choose the correct statement from the options below:

- For the **H atom**:
  - \(3p\) is higher in energy than \(3d\)
  - \(3p\) and \(3d\) are equal in energy
  - \(3p\) is lower in energy than \(3d\)
  - \(3p\) and \(3d\) are equal in energy
  - \(3p\) is higher in energy than \(3d\)

- For the **K atom**:
  - \(3p\) is higher in energy than \(3d\)
  - \(3p\) is lower in energy than \(3d\)
  - \(3p\) and \(3d\) are equal in energy
  - \(3p\) and \(3d\) are equal in energy
  - \(3p\) and \(3d\) are equal in energy

You must determine which of these dual statements correctly describes the energy relationship between the 3p and 3d orbitals in hydrogen and potassium atoms.
