Question

z effective of titanium ​

Answer 1

$\huge\underline\green{\sf Answer}$

$\large{\boxed{\sf Z_{eff}=3.15}}$

$\huge\underline\green{\sf Solution}$

FORMULA TO FIND Z EFFECTIVE IS :-

$\huge{\boxed{\sf Z_{eff}=Z-\sigma}}$

Here,

Z = Nuclear charge

$\sf{\sigma}$ = Screening effect

Now how to find screening effect ?

By Slater's rule

REMEMBER :-

• Screening effect of one electron of 1s is 0.30

• Screening effect of ns and np electron is 0.35

• Screening effect of (n-1) peniultimate orbits s, p, d, electrons is 0.85

• Screening effect of (n-2) and below all the electrons present in s, p, d, f is 1

Here in the question we have to find $\sf{Z_{eff}\:of\:Ti}$ :-

Electronic configuration of Ti = $\sf{{3d}^{2}{4s}^{2}}$

Therefore,

 Z = 4

And According to slater's rule  Screening effect is = 0.85

ON PUTTING VALUE :-

$\large{\sf Z_{eff}=Z - \sigma}$

$\large\implies{\sf 4 - 0.85 }$

$\large{\boxed{\sf Z_{eff}=3.15}}$

Answer 2

Z effective of titanium is 3.15

Explanation:

• In a multi electronic atom, the amount of the total positive charge exerted by the system of electrons is called Z effective.
• Z effective can be calculated using the formula $Z effective = Z - S$, Where Z is the Atomic number of the electron and S is the Number of Screening electron
• In case of an electron, the resisting capacity is called a shielding effect. Proton count determines the atomic number.
