  4. Atomic Model Concepts Place the following concepts where they belong in the diagram above • Atoms cannot be divided • Atoms can be divided into subatomic particles • Atoms contain a small positively charged nucleus • Atoms of the same element all have the same mass and size • Subatomic particles with negative charge are called electrons • Negative electrons revolve around the nucleus • Atoms of different elements have different mass and size • Atoms resemble a raisin bun • Atoms can link together • Nucleus is composed of protons and neutrons • His important discoveries were made in Canada • Atoms are small, hard, and indestructible • His discoveries were made by beaming particles at gold foil
