【】How Many Valence Electrons Does Selenium (Se) Have?|| Selenium (Se) Valence Electrons
 Selenium has six valence electrons. Read:CO2 Lewis Structure Explanation:      Now I am going to show you how to find valence electrons in selenium  in just 5 steps.            Add caption                            Step-1:      First, find the atomic number of  selenium  from periodic table.                  From periodic table ,we see that the atomic number of  selenium  is 34.                                    Step-2:         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.   Read:CO2 Lewis Structure                 Step-3:      Now write the electron configuration of  selenium   .    Se(34)=1s²2s²2p⁶3s²3p⁶4s²3d¹º4p⁴   Rewrite this ...
