Which of the following refers to the region where there is a high probability of finding an electron?
a. electron cloud
b. emission region
c. quantum model
d. electron radius

The correct answer is A. Electron cloud

Explanation:

An electron is a type of particle that can be found orbiting the nucleus of atoms. In the last years, scientists have determined electrons are not in a fixed position but can be found in different zones at a specific time; moreover, electrons behave similarly to waves, which makes it difficult to locate their positions in the atoms. Despite this, there are certain regions in which you will likely find an electron at a certain time, these zones are known as the electron cloud. Thus, the term that refers to the region where there is a high probability of finding an atom is the electron cloud.
