multiple choice question
what is the term for the number assigned to each orbit of an electron?
quantum number
orbital number
energy level number
orbit number

Explanation:

Quantum numbers are used to describe the properties of electrons in an atom, including their energy levels and orbital characteristics. The principal quantum number \(n\) specifically relates to the energy level or "orbit" of an electron. Orbital number is not a standard term in this context. Energy level number is less specific compared to quantum number. Orbit number is an outdated and less accurate term compared to the quantum - mechanical description using quantum numbers.

Answer:

quantum number
