A chemistry student used the symbol "sx" to represent an s orbital that lies along the x-axis. Is this reasonable. Justify your answer.

Isn't an s orbital circular? If so, then how could it lie along the x-axis?

To determine whether it is reasonable to use the symbol "sx" to represent an s orbital that lies along the x-axis, we need to understand the standard nomenclature for orbital symbols.

In chemistry, the standard notation for orbitals follows the form "nL," where "n" represents the principle quantum number and "L" represents the azimuthal quantum number. The principle quantum number (n) indicates the energy level of the orbital, while the azimuthal quantum number (L) specifies the shape and subshell of the orbital.

The azimuthal quantum number (L) can take values from 0 to (n-1), where each value corresponds to a specific type of orbital. For example, when L = 0, it represents an s orbital; when L = 1, it represents a p orbital, and so on.

However, the symbol "sx" deviates from this standard notation since it combines the principle quantum number (n) and the orientation along the x-axis (x). There is no convention for including an axis orientation in the orbital symbol.

Thus, using "sx" to represent an s orbital that lies along the x-axis is not a standard practice. It is important to adhere to established notations and conventions in chemistry to maintain clarity and consistency in scientific communication.

Instead, to represent an s orbital, the standard notation of "s" should be used without any axis orientation specified.
