Selenium (Se) has 6 (2 + 4) valence electrons.

The valence of selenium can vary depending on the type of compound it forms; however, it is typically -2, as it often seeks to gain two electrons to fill its valence shell and achieve a stable noble gas configuration.

Answer (1 of 3): As element 34, it has 34 electrons. 2+8+18 is 28. Therefore, six electrons are on its valence shell. It all depends on shells accepting an amount of electrons.

In the shorthand configuration [Ar] 4s² 3d¹⁰ 4p⁴, the valence electrons are the ones included after the noble gas notation [Ar]. Therefore, underline the 4s² 3d¹⁰ 4p⁴ portion of the configuration to signify that these are the valence ...

Answer (1 of 2): Six. You can easily say this if you remember that Se belongs to Oxygen family. As Oxygen have 6 valence electrons, all it's group members also will have the same.

Conclude that the valence electrons of selenium are located in the 4s and 4p orbitals, not in 3d, 4d, or 4f orbitals.
