• Composed of 3 primary particles
▪ Protons – carries positive charge
▪ Neutrons – carries neutral charge
▪ Electrons – carries negative charge and is smallest particle of atom
Nucleus – central part of an atom and contains nearly all the mass of the atom
▪ 2 kinds of particles are found in nucleus and they are protons and neutrons
▪ particles called electrons move around nucleus in paths called orbits
Molecules – 2 or more atoms lightly attached to one another and act as a unit
Does matter change?

Mixture Examples
▪ breakfast cereal (grains, nuts, raisins)
▪ granite (quartz, hornblende, feldspar)
▪ Muddy water
Solutions
