1. Electron Configuration:
* Bromine (Br) has an atomic number of 35, meaning it has 35 electrons.
* The electron configuration for bromine is: 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵
2. Valence Electrons:
* Valence electrons are the electrons in the outermost energy level (shell).
* For bromine, the outermost shell is the 4th shell (n=4).
* The valence electrons are located in the 4s and 4p orbitals.
3. Specific Orbitals:
* 4s orbital: Contains 2 electrons (4s²)
* 4p orbitals: Contains 5 electrons (4p⁵)
Therefore, the valence electrons of a bromine atom are located in the 4s and 4p atomic orbitals.
