Atoms are negatively charged electrons revolving around a ______ charged nucleus.

Atoms consist of a nucleus that is composed of protons and neutrons. Protons have a positive charge, while neutrons have no charge. The negatively charged electrons orbit around this positively charged nucleus. This positive charge in the nucleus is what attracts the negatively charged electrons, allowing them to maintain their orbit around it.

The interaction between the opposing charges (positive and negative) is fundamental to the structure of the atom, ensuring that the electrons remain bound to the nucleus. If the nucleus were negatively charged, it would repel the electrons, and they would not be able to stay in orbit. Similarly, if the nucleus were neutral (equally charged), there would be no electrostatic force to hold the electrons in orbit. Thus, the positive charge of the nucleus is essential for the stability of the atomic structure.
