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. previous answers correct part b correct the false sentences from the part a. the ti²⁺ ion contains 20 protons and 24 electrons. the ti²⁺ ion contains 24 protons and 22 electrons. the ti²⁺ ion contains 22 protons and 20 electrons. the ti²⁺ ion contains 24 protons and 26 electrons.

Explanation:

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

The atomic number of \(Ti\) (titanium) is \(22\), so it has \(22\) protons. For \(Ti^{2+}\), since it has a \(+2\) charge, the number of electrons is \(22 - 2=20\). So the statement "The \(Ti^{2 +}\) ion contains 22 protons and 24 electrons" is false.

Step2: Analyze the \(I^{-}\) ion

The atomic number of \(I\) (iodine) is \(53\), so it has \(53\) protons. For \(I^{-}\), since it has a \(- 1\) charge, the number of electrons is \(53+1 = 54\). So the statement "The \(I^{-}\) ion contains 53 protons and 54 electrons" is true.

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

The atomic number of \(Mg\) (magnesium) is \(12\), so it has \(12\) protons. For \(Mg^{2+}\), since it has a \(+2\) charge, the number of electrons is \(12 - 2=10\). So the statement "The \(Mg^{2 +}\) ion contains 14 protons and 12 electrons" is false.

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

The atomic number of \(O\) (oxygen) is \(8\), so it has \(8\) protons. For \(O^{2-}\), since it has a \(-2\) charge, the number of electrons is \(8 + 2=10\). So the statement "The \(O^{2 -}\) ion contains 8 protons and 10 electrons" is true.

Answer:

The true statements are: "The \(I^{-}\) ion contains 53 protons and 54 electrons" and "The \(O^{2 -}\) ion contains 8 protons and 10 electrons". For the correction of the \(Ti^{2+}\) ion statement, the correct option is "The \(Ti^{2 +}\) ion contains 22 protons and 20 electrons".
