Worked Solution & Example Answer:Bohr's model of the atom explained the existence of energy levels on the basis of atomic spectra - Leaving Cert Chemistry - Question (iv) and (v) - 2006
Step 1
Define atomic orbital.
Answer
An atomic orbital is defined as a region around the nucleus of an atom where there is a high probability of finding an electron. This can also be described as a space in which the electron is most likely to be found, represented mathematically by the wave function obtained from the solution of Schrödinger's equation. Thus, an atomic orbital reflects both the location and the spatial distribution of the electron around the nucleus.
Step 2
What does Heisenberg's uncertainty principle say about an electron in an atom?
Answer
Heisenberg's uncertainty principle asserts that it is impossible to simultaneously measure both the exact position and the exact momentum (or velocity) of an electron in an atom. This inherent limitation arises from the wave-particle duality of electrons; the more precisely one property is measured, the less precisely the other can be known. Consequently, there exists a fundamental limit to our ability to predict the behavior of quantum particles.
