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.
C. D. 3 2 ” in Chemistry if there is no answer or all answers are wrong, use a search Concept introduction: The total number of electrons present in an atom is equal to its atomic number. 4. 2.
2008-11-03 · Total valence electrons = 6 + 28 = 34. Eight electrons are used up for the four Se-F single bonds, leaving 26 nonbonding electrons, 2 around the Se atom and 6 around each of the four F atoms. Se and F can't form double bonds.
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. Four Quantum Numbers: Principal, Angular Momentum, Magnetic & Spin. Selenium (34 Se) has Valence Electrons. The electronic configuration of an atom is given by listing its subshells with the number of electrons in each subshell, as shown in Table 1.

Valence electrons, their variation in the periodic table and relation to reactivity and electrical conductivity of elements.
Tin is located in group 1color(red)(4) of the periodic table, which means that it has color(red)(4) electrons in its outermost shell, i.e. 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.
