When we study the trends in the periodic table, we cannot stop at just atomic size. In this section of the chapter, we will begin an understanding of an important concept, namely ionization energy and recognize its trend on the Periodic Table. Define ionization energy....of sr? a. sr (g) → sr+ (g) + e- b. sr2+ (g) + e- → sr+ (g) c. sr+ (g) + e- → sr (g)" in Chemistry if there is no answer or all answers are wrong, use a The following ionization energies were found for an unknown element: - 1st Ionization Energy 9.32270 eV. What is the ionization reaction for HNO3.Which reaction below represents the second ionization of Ba?a. sr(g) → sr⁺(g) + e⁻ b. sr2⁺(g) + e⁻ → sr⁺(g) c. sr⁺(g) + e⁻ → sr(g) d. sr⁻(g) + e⁻ → sr2⁻(g) e. sr⁺(g) → sr2⁺(g) + e⁻?
