List the 5 Statements of Daltons Atomic Theory
- All matter is made up of very small particles called atoms
- All atoms are indivisible. They cannot be created nor destroyed.
- All atoms of a chemical element are equal. Their only difference to other atoms is their mass.
- Atoms can form chemical bonds. These bonds can also be released.
- The smallest particles of a compound are always made up of the same number of atoms.
What did Ernest Rutherford explore?
Atoms consist of a small positively charged nucleus and a negatively charged sphere.
How do you call protons and neutrons?

Sphere.
Explain Rutherfords Scattering Experiment
A large quantity of the
α-radiation passes through gold foil
A small part of the
α-radiation hits the nucleus and is diffracted.
The atomic number
- shows the number of protons in the nucleus
- ist die untere Zahl von den Beiden
- determines the position in the periodic table
- number of electrons in the sphere of a non-charged atom
