Question

the quantum mechanical model of the atom ____.
defines the exact path of an electron around the nucleus
involves the probability of finding an electron in a certain position
has many analogies in the visible world
was proposed by niels bohr

Explanation:

The quantum mechanical model of the atom is based on the wave - particle duality of electrons. It does not define an exact path for electrons (unlike the Bohr model). Instead, it uses wave functions to calculate the probability of finding an electron in a particular region of space (an orbital). The Bohr model was proposed by Niels Bohr and had electrons in fixed circular paths. The quantum mechanical model is a more abstract and less intuitive model compared to the visible - world analogies.

Answer:

involves the probability of finding an electron in a certain position
