How many valence electrons are in selenium se
Webselenium (Se), a chemical element in the oxygen group (Group 16 [VIa] of the periodic table), closely allied in chemical and physical properties with the elements sulfur and tellurium. Selenium is rare, composing approximately 90 parts per billion of the crust of Earth. It is occasionally found uncombined, accompanying native sulfur, but is more often … WebSelenium is a member of the sulfur family with elements including tellurium and polonium. This family has six electrons in the outermost shell. 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 valence numbers. Selenium compounds have been found that ...
