Here's a breakdown:
* The nucleus is positively charged due to the presence of protons.
* Electrons are negatively charged.
* Opposite charges attract. This means the positive nucleus attracts the negatively charged electrons, keeping them bound to the atom.
It's important to note that the orbits of electrons aren't quite like the orbits of planets around a star. The electrons exist in orbitals, which are regions of space where the probability of finding an electron is high. These orbitals are governed by quantum mechanics and are not simple circular paths.
So, while the force is analogous to gravity pulling planets into orbit, the details of how electrons behave in an atom are much more complex.
