Examples

A fast proton moving through matter will slow by interactions with electrons and nuclei, until it is captured by the electron cloud of an atom. Source: Internet

Like a dipole-induced dipole force, the charge of the ion causes distortion of the electron cloud on the non-polar molecule. Source: Internet

As a result, the electron cloud contracts and the atomic radius decreases. Source: Internet

As the nuclear charge of the nucleus increases across the period, the atomic radius decreases and the electron cloud becomes closer towards the nucleus. Source: Internet

Depicted are the nucleus (pink) and the electron cloud distribution (black). Source: Internet

If electrons 'move' about the electron cloud in strict paths the same way planets orbit the sun, then electrons would be required to do so at speeds which far exceed the speed of light. Source: Internet
