The quantum mechanical model of the atom a. defines the exact path of an electron around the nucleus b. was proposed by niels bohr c. involves finding an electron somewhere in a specific orbital d. has many analogies in the visible world

Quantum mechanical model = involves finding an electron somewhere in a specific orbital.

Explanation:

The quantum mechanical model of an atom involves finding an electron somewhere in a specific orbital. This method is completely based on mathematical calculations. It defines the probability of finding an electron rather than its reality.

These are designated by some letters like s, p, d, f and the corresponding energy levels are 1st, 2nd, 3rd and so on

So, the correct option is (c) "involves finding an electron somewhere in a specific orbital".

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
