Answer:
Although the question is not clear enough, I'll explain in the most helpful way that I can.
Explanation: The Quantum Mechanical Model of the atom is one of two models that explains the structure of an atom. In this model, it is imposssible to know the exact position and momentum of an electron at the same time and thus its position is uncertain. However, electrons are said to occupy three dimensional regions of probability referred to as 'ORBITALS'. You can simply refer to the orbitals as where there is very high likelihood for one or two electrons to be found. Each of these orbials are depicted with a number, n and a letter(s,p,d,f or g) eg 1s, 2p, etc. The 'number' signifies the distance of the orbital from the nucleus and the energy level of the electron in an atom while the 'letter' indicates the shape of the orbital, for example, the s-orbital is spherical in shape.
I hope this helps!
