Ionization is the process of removing an electron from an atom. For an atom, X , X, the first and second ionizations are described by the following equations. First ionization: X ( g ) ⟶ X + ( g ) + e − First ionization: X(g)⟶X+(g)+e− Second ionization: X + ( g ) ⟶ X 2 + ( g ) + e − Second ionization: X+(g)⟶X2+(g)+e− Consider the ionization of the period 2 2 elements. Which element has the highest second ionization energy? boron (B) oxygen (O) nitrogen (N) beryllium (Be) carbon (C) fluorine (F) lithium (Li) neon (Ne) Which element has the lowest second ionization energy? fluorine (F) beryllium (Be) nitrogen (N) neon (Ne) lithium (Li) carbon (C) oxygen (O) boron (B)
