Question

an atomic scientist was studying an atom and through experiment area surrounding the nucleus is -9. which statement correctly de: 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 and are found in the area surrounding the nucleus. Neutrons are neutral and protons are positively - charged, both located in the nucleus. Electron clouds are regions where electrons are likely to be found, but the charge value directly indicates electrons. Since the charge in the area surrounding the nucleus is - 9, it means there are nine negatively - charged electrons.

Answer:

This atom has nine electrons.
