Se– has a total of 7 valence electrons.
In this way, how do you write the electron configuration for SE?
Similarly one may ask, how many core and valence electrons does SE have? When we look at the electron configuration for Selenium (Se), we see the following. There are 28 core electrons (1s22s22p63s23p63d10) and six valence electrons (4s24p4). Again, none of the core electrons from either of these elements, or any element for that matter, will participate in chemical reactions.
Additionally, how many neutrons does SE have?
45 neutrons
How many valence does silicon have?
Four valence electrons
