Question

Predict the highest and lowest oxidation state of $\left(a\right)Ti$ and $\left(b\right)Tl$ in combined state.

• A. $a[0,+3]b[0,+2]$
• B. $a[+3,0]b[+4,0]$
• C. $a[+4,0]b[+4,0]$
• D. $a[+4,+2]b[+3,+1]$

Answer 1

Answer: (D)

$a[+4,+2]b[+3,+1]$

Outer shell configuration of $Ti$ is :

$\left[Ar\right]3d^{2}4s^2$

It minimum state it will remove outer electrons

and at maximum it will remove both d and

b structures.

For $Tl:\left[Xe\right]4f^{14}5d^{10}6s^{2}6p^1$

For minimum states it will remove p electrons

and at maximum all 3 bth shall

electrons will be removed.
