Question

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.

Explanation:

Electrons are negatively - charged particles that surround the nucleus. Each electron has a charge of - 1. So, if the total negative charge around the nucleus is - 9, there must be nine electrons. Neutrons are neutral and protons are positively - charged. Electron clouds are regions where electrons are likely to be found, not directly related to the total negative charge value in this context.

Answer:

This atom has nine electrons.
