Particle Diagrams of Chemical and Physical Changes

A physical change should

• never change mass

• change the shape and color of particles

• keep the same shape and color of particles

• form a new substance

If a change causes the mass to decrease

• more particles should be present in the after diagram.

• A compound should break apart.

• less particles should be present in the after diagram.

• elements should combine to form compounds.

In a sealed container or closed system

• The particles never change

• The number of particles stays the same

• The particles cannot change shape

• The particles cannot change color.

When a metal combines with oxygen to form rust or oxidation

• new particles enter the system

• particles are lost from the system

• a physical change takes place

• the mass stays teh same
