According to the wave mechanical model of the atom, where are the electrons of an atom most likely to be found?
A
In fixed circular paths around the nucleus
B
Only at specific energy levels without any overlap
C
In regions of space called orbitals, where there is a high probability of finding an electron
D
Randomly distributed throughout the entire atom
Verified step by step guidance1
Understand that the wave mechanical model of the atom describes electrons not as particles moving in fixed paths, but as wave-like entities with probabilities of location.
Recall that in this model, electrons are found in regions called orbitals, which are defined by mathematical functions describing the probability distribution of an electron's position.
Recognize that orbitals are not fixed paths or shells but are three-dimensional regions where the probability of finding an electron is high.
Note that these orbitals can overlap and are associated with specific energy levels, but electrons are not confined to exact circular orbits.
Conclude that the correct description is that electrons are most likely found in orbitals—regions of space with a high probability of electron presence—rather than fixed paths or random distribution.
