Post navigation. The groups are the Since selenium is in column 18 of the periodic table, it needs 2 electrons to be Selenium that most people do n't know follows shows the valence electrons for 27 Feb 2021 From periodic table ,we see that the atomic number of selenium is 34. Possible oxidation states are -4; -3 …; + 4. Valence electron shells in the There are two core electrons (1s 2) and two valence electrons (2s 2).When we look at the electron configuration for Selenium (Se), we see the following. Learn the octet rule and how it applies to electron energy levels.

It all depends on shells accepting an amount of electrons. Selenium specifically has an electron configuration of 2-8-18-6. The six electrons in the outermost shell allow selenium to have a variety of valencenumbers. Selenium compounds have been found that have valences of -2, 4, and 6.

color(red)(4) valence electrons. Valence electrons are the total number of electrons present in the outermost shell of an atom (i.e. in outermost orbital). The valence electron for a neutral atom is 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.

Inert atoms have completed shells with the maximum number of valence electrons. For transition metals, some inner electrons also act as valence electrons. The number of valence electrons can be determined by looking at the electron configuration of the atom. 2019-02-11 · Another way to think of valence electrons is that they are the outermost electrons in an atom, so they are the most susceptible to participation in chemical bond formation or ionization. The simplest way to identify the valence electrons is to look for the highest number in the electron configuration of an atom (the principal quantum number).
