12) Choose the best electron-dot structure for OCl 2. How many valence electrons are in an atom of Se? Therefore, the number of electrons in neutral atom of 

The valence electrons for a neutral atom are always definite, it cannot be varied (more or less) in any condition for a particular atom and may or may not be equal to its valency. Electrons de valence: définition Définition: Les électrons de valence d’un atome sont les électrons appartenant à la couche de valence d’un atome. Ce sont les électrons dont l’orbite est la plus éloignée du noyau et qui sont les plus exposés aux autres entités chimiques. Valence electrons are the s and p electrons in the outermost shell. The electrons present in the inner shell are core electrons. When we study and observe the atom of an element, we come across tiny subatomic particles called valence electrons. Lewis structures help us to track the valence electrons and predict the types of bond.

We know that the atomic number of selenium is 34.So selenium has 34 protons and 34 electrons as the charge of electrons and protons are equal but opposite in nature.The charge of proton is +1 and the charge of electron is -1. Step-3: Now write the electron configuration of selenium . Se (34)=1s²2s²2p⁶3s²3p⁶4s²3d¹º4p⁴.
