Question

What situation could produce ultraviolet radiation?

A) Movement of an electron from n = 2 to n = 1
B) Movement of an electron from n = 4 to n = 2
C) Movement of an electron from n = 3 to n = 1
D) Movement of an electron from n = 5 to n = 2

Answer 1

Ultraviolet radiation can be produced when an electron moves from a higher energy level to a lower energy level in an atom. The correct option that could produce ultraviolet radiation is D) Movement of an electron from n = 5 to n = 2.

Step-by-step explanation:

Ultraviolet radiation can be produced by the movement of an electron from a higher energy level to a lower energy level in an atom.

Specifically, when an electron moves from an orbit with a higher principal quantum number, such as n = 5, to an orbit with a lower principal quantum number, such as n = 2, ultraviolet radiation is emitted.

Therefore, the correct option that could produce ultraviolet radiation is D) Movement of an electron from n = 5 to n = 2.
