Question

Would you expect the electronegativity of titanium to be the same in the species Ti, Ti²⁺, Ti³⁺, and Ti⁴⁺? Explain.

Short answer

Answer

Titanium is a transition metal with a d subshellthat takes part in bond formation. The order of electronegativity is as below.

Step-by-step solution

Describing the electronegativity

Electronegativity is the tendency of an atom to receive an electron from shared electron pair.

Electronegativity order of the Titanium atom/ions in increasing order be defined as

Ti < Ti²⁺ < Ti³⁺ < Ti⁴⁺

As the electrons are removed from the valence shell the positive charge increases. The charge increment gives rise to the contraction of atom size.

Describing the factors that affect the Electronegativity of different ions/atoms

An increase in positive charge on atoms/ions indicates thatatomic size decreases due to effective nuclear charge.

Also,larger atomic sizedefines the lesser electronegativity because electrons are atthe far end from the nucleus so nuclear attraction will be less for far end electrons.

Hence, we can define that Ti⁴⁺ is more electronegative compared to Ti³⁺, Ti^2+, and Ti.
