Identify the correct sequence of number of unpaired electrons of the following ions. a) Ti+3> Cr3+> Fe3+> Ni2+ b) Fe3+> Ni2+> Ti+3> Cr3+ c) Fe3+ > Cr3+> Ni2+ > Ti+3 d) Fe3+ > Cr3+>... Identify the correct sequence of number of unpaired electrons of the following ions. a) Ti+3> Cr3+> Fe3+> Ni2+ b) Fe3+> Ni2+> Ti+3> Cr3+ c) Fe3+ > Cr3+> Ni2+ > Ti+3 d) Fe3+ > Cr3+>Ti+3> Ni2+
Understand the Problem
The question is asking to identify the correct order of unpaired electrons in the ions of titanium (Ti), chromium (Cr), iron (Fe), and nickel (Ni) based on their charges. We need to consider the electronic configurations of these ions to determine the number of unpaired electrons in each case.
Answer
Fe3+ > Cr3+ > Ti+3 > Ni2+.
The correct sequence is Fe3+ > Cr3+ > Ti+3 > Ni2+.
Answer for screen readers
The correct sequence is Fe3+ > Cr3+ > Ti+3 > Ni2+.
More Information
In transition metal ions, the number of unpaired electrons determines their magnetic properties. More unpaired electrons result in a higher magnetic moment. Fe3+ has 5, Cr3+ has 3, Ti+3 has 1, and Ni2+ has 2 unpaired electrons.
Tips
A common mistake is not correctly counting unpaired electrons based on the electronic configuration.
