What’s needed to build a neutral atom?

Protons are positively charged, electrons are negatively charged (with the same magnitude of charge per particle as a proton). Neutrons have no charge. Now, in a "neutral atom", the number of protons must be equal to the number of electrons, otherwise it would not be neutral.

Explanation:

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
