WebThe three bonds of the triple bond are a total of six electrons and the lone pair is another two electrons giving carbon a total of eight electrons which is what it would like to have. Same thing with nitrogen, it starts with five electrons as a single atom but also wants to attain eight valence electrons following the octet rule. WebThe presence of valence electrons can determine the element's chemical properties and whether it may bond with other elements: For a main group element, a valence electron can only be in the outermost electron shell. An atom with a closed shell of valence electrons (corresponding to an electron configuration s p ) tends to be chemically … chip putty
