Question

determine whether each of the following is true or false.
check all that is true.

the ti²⁺ ion contains 22 protons and 24 electrons.
the i⁻ ion contains 53 protons and 54 electrons.
the mg²⁺ ion contains 14 protons and 12 electrons.
the o²⁻ ion contains 8 protons and 10 electrons.

Explanation:

Step1: Analyze \( \text{Ti}^{2+} \)

The atomic number of Ti (titanium) is 22. For \( \text{Ti}^{2+} \), protons = 22 (atomic number). Electrons = 22 - 2 = 20 (not 24). So this statement is false.

Step2: Analyze \( \text{I}^{-} \)

The atomic number of I (iodine) is 53. For \( \text{I}^{-} \), protons = 53 (atomic number). Electrons = 53+1 = 54. So this statement is true.

Step3: Analyze \( \text{Mg}^{2+} \)

The atomic number of Mg (magnesium) is 12. For \( \text{Mg}^{2+} \), protons = 12 (atomic number). Electrons = 12 - 2 = 10 (not 12). So this statement is false.

Step4: Analyze \( \text{O}^{2-} \)

The atomic number of O (oxygen) is 8. For \( \text{O}^{2-} \), protons = 8 (atomic number). Electrons = 8+2 = 10. So this statement is true.

Answer:

The \( \text{I}^{-} \) ion contains 53 protons and 54 electrons (True). The \( \text{O}^{2-} \) ion contains 8 protons and 10 electrons (True).
