Recognize that the space surrounding the nucleus is where electrons are found, and electrons carry a negative charge.
Identify that the region containing electrons around the nucleus is called the electron cloud.
Conclude that the electron cloud is the part of the atom with an overall negative charge surrounding the nucleus.
