An atomic scientist was studying an atom and through experimentation found that the total negative charge of the area surrounding the nucleus is -9. Which statement correctly describes this atom?

This atom has nine clouds.
This atom has nine electrons.
This atom has nine neutrons.
This atom has nine protons.

The statement that correctly describes the atom is:

This atom has nine electrons.

In an atom, the total negative charge is due to the electrons, as they carry a negative charge. If the total negative charge surrounding the nucleus is -9, it indicates the presence of nine electrons, since each electron has a charge of -1. The other options regarding clouds, neutrons, and protons do not directly relate to the negative charge mentioned in the context of electrons.
