3. Determine the Zeff value of Uranium, also indicate (based on your answer with mathematical calculations) which electron will
Ilya [14]

Explanation:

Electronic configuration of uranium is given below -

1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶4d¹⁰5s²5p⁶4f¹⁴5d¹⁰6s²6p⁶5f³6d¹7s2²

Effective nuclear charge (Z eff) = Atomic number (Z) - Shielding constant (S)

<u> Value of Shielding constant (S) can be calculated by using slater's rule : </u>

S = 1 (0.35) + 9 (0.85) + 81 (1.00)

S = 0.35 + 7.65 + 81.00

S = 89

So,

Zeff = Z - S

Zeff = 92 - 89

<u> Zeff = 3 </u>

Hence, Effective nuclear charge (Zeff) of uranium = <u>3 </u>

5s electron is closest to the nucleus.

A sample of Francium-212 will decay to one sixteenth of its original amount after 80 minutes. What is the half-life of Francium-
lbvjy [14]

20 minutes.

The sample would lose one half the quantity of francium in each half-life.

1/16 = 1/2^{4} = 1/2 \times1/2 \times1/2 \times1/2

Thus a mass decrease by a factor of 16 would correspond to a period of four half-lives. It took 80 minutes for the sample to lose all these francium, therefore

t_{1/2} = 80/4 = 20 minutes.
