Electrons do not travel around the nucleus in orbits like planets around the sun. The current model of the atom, called the quantum mechanical model, describes electrons as existing in orbitals, which are regions of space where there is a high probability of finding an electron.

Here's why the term "orbit" is inaccurate:

* Electrons don't follow a defined path: Unlike planets, electrons don't move in predictable circular paths. Their movement is more like a cloud or a fuzzy sphere.

* Quantum mechanics: The behavior of electrons is governed by quantum mechanics, which means their position and momentum can't be known with absolute certainty.

So, the correct term is orbitals, not orbits.
