No, Selenium (Se) and Bromine (Br) do not have the same number of valence electrons.

Here's why:

* Selenium (Se): Selenium is in Group 16 (VIA) of the periodic table. Elements in this group have 6 valence electrons.

* Bromine (Br): Bromine is in Group 17 (VIIA) of the periodic table. Elements in this group have 7 valence electrons.

Therefore, Selenium has 6 valence electrons, while Bromine has 7 valence electrons.
