1 Jan 1853 Jahr - Evidence Arises

Beschreibung:

Approximately fifty years after John Dalton's proposal of the atom, evidence began to accumulate which suggested that the atom might not be the solid sphere that Dalton had envisioned. This evidence came in the form of the discovery of electrically charged particles and radioactive materials. Based on these new discoveries, Dalton's proposal of a solid, indestructible atom became unacceptable.
