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.

Element Selenium (Se), Group 16, Atomic Number 34, p-block, Mass 78.971. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and 

In the case of Antimony the valence electrons is 0,-3,3,5. Now let's check the facts about Antimony Antimony Overview Antimony Valence Electrons 0,-3,3,5 Atomic Number 51 To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. A Lewis electron dot diagram (or electron dot diagram, or a Lewis diagram, or a Lewis structure) is a representation of the valence electrons of an atom that uses dots around the symbol of the element.

Learn the octet rule and how it applies to electron energy levels. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin. Selenium (34 Se) has  

The Group 3 atoms have 3 valence electrons. The Group 4 atoms have 4 valence electrons.

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.

Ok but how many valence electrons does an atom of Antimony have? In the case of Antimony the valence electrons is 0,-3,3,5.

Whatever the type of chemical bond (ionic, covalent, metallic) between atoms, changes in the atomic structure are restricted to the outermost, or valence, electrons. Sub-shells s, p, d and f hold a maximum of two, six, 10 and 14 electrons, respectively. In selenium, the first energy level has two electrons in sub-shell s. The second energy level holds eight electrons.

The presence of valence electrons can determine the element's chemical properties, such as its valence—whether it may bond with other elements and, if so, how readily Se has 6 valence electrons, but if you add the ion Se2- you're going to be gaining 2 electrons, in which you'll have 8 valence electrons. Valence electrons are characteristics of metals. Selenium is a nonmetal. It accepts electrons, rather than releases them.
