Valence Electrons in Bromine
Valence electrons are the electrons in the outermost shell that participate in chemical bonding. For bromine, the relevant electrons are:
- 3s² (2 electrons)
- 3p⁵ (5 electrons)
This means bromine has a total of **7 valence electrons**. The 3d orbital is not involved in the valence shell for bromine, as it is filled in elements with higher atomic numbers.
Summary
In summary, the valence electrons of bromine are located in the 3s and 3p orbitals, not in the 3d orbital.
