which ion was formed by providing the second ionization energy to remove an electron?\nca²⁺\nn³⁻\nfe³⁺\ns²⁻
Answer
Brief Explanations:
Second - ionization energy is the energy required to remove an electron from a + 1 ion. Calcium (Ca) has an atomic number of 20. The first ionization of Ca gives Ca⁺, and the second ionization gives Ca²⁺. Nitrogen (N) forms N³⁻ by gaining electrons. Iron (Fe) forms Fe³⁺ through multiple ionizations starting from neutral Fe, not directly from a + 1 state for the third - ionization step. Sulfur (S) forms S²⁻ by gaining electrons.
Answer:
Ca²⁺
