He accepted, but later confessed he had never heard her music. the existence of light quantum, or packets of energy. 330-333. Surrounding this tiny central core were electrons, and the distance at which they orbited determined the size of the atom. That's because matter is usually electrically neutral; so if atoms contain negatively charged particles, they must also contain a source of equivalent positive charge to balance out the negative charge.
