Final answer:

The atom with a total negative charge of -9 has nine electrons.


Explanation:

The correct statement describing the atom with a total negative charge of -9 is:

  • This atom has nine electrons.

In an atom, the negative charge comes from electrons. Since the total negative charge of the area surrounding the nucleus is -9, it means there are nine more electrons than protons in the atom.

Remember, in a neutral atom, the number of electrons equals the number of protons resulting in no net charge.
