Matter

Anotações:

• Everything in this world is made up of tiny particles called "atoms", and each atom is the made up of “protons", "neutrons", and "electrons."

1. Insulators

   Anotações:

   • These materials are made up of atoms which hold their electrons with a stronger force. Electrons could not flow freely from one atom to another - high resistivity.
2. Conductors

   Anotações:

   • These materials are made up of atoms which hold their electrons with a loose force. Electrons could flow freely from one atom to another - low resistivity.
3. Neutral
