When we make the molecular orbital energy level diagram of f2 molecule then, we will get this configuration: 1σs 2, 1σ*s 2, 2σs 2, 2σ* 2, σ2pz 2, π2p x2, π2p y2, πp x * 2, π2p y * 2. From this electronic configuration, we can see that there are a total of ten bonding molecular orbitals and eight antibonding molecular orbitals.

An electron in a low energy level can absorb energy and undergo a transition to a higher energy level. When that electron returns to the ground state, it loses energy by emitting a photon, which is a tiny particle that behaves like a wave and travels at the speed of light.

It seems that I can't wrap my head around the concept of the k-vector and crystal momentum. From my waves course I remember that the wave vector sorta represents where the wave propagates (in an isotropic and homogeneous material). So in solid state that could be thought as the same thing applied to the wave function, right? And here comes the troubles: why and how is it related to the momentum of a particle? I think I get the math behind it but not the concept. Furthermore, given th...

The first orbital, as always, has to be 1s. Since the graph goes up to 2, there are 2 electrons in the 1s orbital. The next orbital has to be 2s and the PES indicates there are 2 electrons in this orbital. So far, the electron configuration seems to be 1s^2 2s^2. There is one more peak though, which corresponds to the 2p orbital.
