which ion was formed by providing the second ionization energy to remove an electron?\no ca²⁺\no n³⁻\no fe³⁺\no s²⁻
Answer
Explanation:
Step1: Understand ionization energy concept
Ionization energy is energy to remove an electron. Second - ionization energy is for removing an electron from a + 1 ion.
Step2: Analyze each option
- For $Ca^{2 + }$: First ionization of Ca gives $Ca^{+}$, second gives $Ca^{2+}$.
- For $N^{3 - }$: Nitrogen gains electrons to form anions, not related to second - ionization energy concept here.
- For $Fe^{3+}$: First ionization of Fe gives $Fe^{+}$, second gives $Fe^{2+}$, third gives $Fe^{3+}$.
- For $S^{2 - }$: Sulfur gains electrons to form anions, not related to second - ionization energy concept here.
Answer:
$Ca^{2+}$
