Chapter 36: Problem 49

Determine the electronic configuration of copper.

Short Answer

Expert verified
The electronic configuration of Copper (Cu) is given by: 1s2, 2s2, 2p6, 3s2, 3p6, 4s1, 3d10.

Step by step solution

01

Identify the element

The element given is Copper (Cu). It's atomic number is 29, which means it has 29 electrons in its neutral state.
02

Apply the Aufbau Principle

According to the Aufbau Principle, electrons fill from the lowest to the highest energy levels. The order of filling goes: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, and so on. Filling according to this order: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d9.
03

Consider the stability of d orbitals

Note that d orbitals are more stable when completely filled (d10) or half filled (d5). Thus, one of the electrons in the 4s orbital will be excited to fill the 3d orbital. This gives: 1s2, 2s2, 2p6, 3s2, 3p6, 4s1, 3d10.

Singly ionized oxygen (so-called O-II) is a prevalent species in the tenuous gas between stars, and O-II emits a doublet spectral line at \(372.60 \mathrm{nm}\) and \(372.88 \mathrm{nm} .\) Astrophysicists analyze this line to learn, among other things, about the distribution of interstellar gas in distant galaxies. Find the energy splitting, in eV, that results in this doublet.

Why is there no spin-orbit splitting in hydrogen's ground state?

A hydrogen atom is in an \(F\) state. (a) Find the possible values for its total angular momentum. (b) For the state with the greatest angular momentum, find the number of possible values for the component of \(\vec{J}\) on a given axis.

Why is stimulated emission essential for laser action?

A harmonic oscillator potential of natural frequency \(\omega\) contains eight electrons and is in its lowest-energy state. (a) What is its energy? (b) What would the lowest energy be if the electrons were replaced by spin- 1 particles of the same mass?
