How many valence electrons are in no
Web29 sep. 2014 · Ian. 151 5. 1. The definition of a valence electron is an electron involved in bonding. As the electrons in the 3rd shell of K are not involved in bonding, it does not make sense to call them valence electrons. K forms metallic bonds with its one 4s electron, and ionic bonds by giving it up to form K+. WebIn the periodic table, Oxygen belongs to the VIA group and has six electrons in its final shell. Carbon is a member of the IVA group and has four electrons in its valence shell. Therefore, the total number of valence electrons required to draw the Lewis structure of CO 2 = 6 (2) + 4 = 16 2.
