Main Answer:
An orbital is a probable space around a nucleus where electrons are likely, embodying quantum mechanics' probabilistic nature in atoms. True.
Therefore, the correct answer is True.
Step-by-step explanation:
An orbital is indeed a region of space around the nucleus where an electron is likely to be found. In the quantum mechanical model of the atom, electrons are not confined to specific orbits, as in the classical model, but are rather described by probability distributions known as orbitals. These orbitals represent the regions where electrons are most likely to be located, and the shape of the orbital indicates the probability density at different points within that region.
The statement reflects the probabilistic nature of electron behavior as described by quantum mechanics. It's important to note that orbitals don't prescribe exact paths for electrons but rather define the likelihood of finding an electron within a certain space around the nucleus. The concept of orbitals helps us understand the distribution of electrons in an atom, which is crucial for explaining various chemical and physical properties.
In summary, the statement is true because an orbital is a mathematical function that describes the wave-like behavior of electrons, providing a way to predict the likelihood of finding an electron in a particular region of the atom. Understanding orbitals is fundamental to comprehending the electronic structure of atoms and, consequently, the behavior of matter at the atomic level.
Therefore, the correct answer is True.
