Elements in the period of this number are the first to have g electrons. Many compounds containing this number of carbons may be obtained by dimerizing butadiene. This is xenon's highest oxidation state, and also the highest oxidation state observed for any element. The element of this atomic number forms the lightest homonuclear triatomic molecule and is also the most abundant element in the crust by mass. All the noble gases past helium have this many valence electrons
Elements in the period of this number are the first to have g electrons. Many compounds containing this number of carbons may be obtained by dimerizing butadiene. This is xenon's highest oxidation state, and also the highest oxidation state observed for any element. The element of this atomic number forms the lightest homonuclear triatomic molecule and is also the most abundant element in the crust by mass. All the noble gases past helium have this many valence electrons, as one expects based on a rule named for this number. For 10 points, what is the atomic number of oxygen and the number of carbons in octane?
Elements in the period of this number are the first to have g electrons.
