Chapter 23: Q 2P (page 1058)

Question: Write the general electron configuration of a transition element
(a) In Period 5;
(b) In Period 6.

Short Answer

Expert verified

The electron configuration in general is: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{10} 4 p^{6} 5 s^{2} 4 d^{x}$
The arrangement is: $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{10} 4 p^{6} 5 s^{2} 4 d^{10} 5 p^{6} 6 s^{2} 4 f^{14} 5 d^{x}$

Step by step solution

Define General electron configuration

The arrangement of orbital energy levels for s, p, d, and f-block elements of the periodic table is known as the general electron configuration or electronic structure of atoms or ions.

For the general electron configuration of a transition element

All transition elements in Period 5 have the same "base" configuration of $[Kr] 5 s^{2}$ , but the quantity of d electrons $(x)$ in that configuration varies.

As a result, the electron configuration in general is:

$1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{10} 4 p^{6} 5 s^{2} 4 d^{x}$

Finding for period six

The f sublevel electrons are lower in energy than the d sublevel electrons in a generic electron configuration for Period 6 transition elements.

As a result, the arrangement is $1 s^{2} 2 s^{2} 2 p^{6} 3 s^{2} 3 p^{6} 4 s^{2} 3 d^{10} 4 p^{6} 5 s^{2} 4 d^{10} 5 p^{6} 6 s^{2} 4 f^{14} 5 d^{x}$
