How many unpaired electrons does selenium have in its 4p orbital? They have one or two valence electrons, so they cannot lose electrons easily. How does the number of valence electrons in atoms of metalloids explain why metalloids are semiconductors? The inorganic chemistry textbooks that I studied from talk extensively about sulphur and, where appropriate, say things like 'selenium also forms similar acids', or 'selenium also has many allotropic forms'. Boron (B) 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. This means the first shell (1s) has 2 electrons. Selenium is a chemical element.Its chemical symbol is Se and its atomic number is 34. 2+8+18 is 28. This table shows the pattern in the periodic table that Mendeleev developed and how the missing elements at that time could be predicted. Click on element #42 and scroll down the menu on the left side until you come to To identify an element's valence or outermost electrons, you can refer to its group number on the periodic table.
