Chapter 7: Problem 92

Use the Aufbau principle to obtain the ground-state electron configuration of technetium.

Short Answer

Expert verified
The ground-state electron configuration of Technetium, using the Aufbau principle, is \(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^6 5s^2 4d^5\).

Step by step solution

01

Identify the atomic number of Technetium

Technetium is the 43rd element in the periodic table, so it has 43 electrons in its neutral state.
02

Apply the Aufbau principle

Start filling the electrons in the ascending order of energy level. Following the Aufbau principle, the electron configuration of neutral state Technetium would be \(1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4p^6 5s^2 4d^5\). Here, each power represents the number of electrons in that orbital.
