Rather, electrons must occupy a band of energy levels.

Like making an electron occupy an entire room with a single, prodigious quantum state.

This meant that the electrons could only occupy orbits at certain energies.

In difluorine two additional electrons occupy the 2pπ with a bond order of 1.

Not only are the electrons occupying the space, but they repel each other as a result of their electric charges.

In this state, matter is so dense that further compaction would require electrons to occupy the same energy states.

The single electron then occupies the lower orbital, d z 2, and the overall energy of the system is reduced.

These quantum dots are sites electrons can occupy by tunneling to them.

The electrons in an atom, he said, occupy quantized orbits.

In certain semiconducting environments, electrons occupy something called a quantum well.
