Magnetism -the attraction of a magnet for another object -two magnets will either attract or repel each other -if the domain inside a magnet are aligned it’s magnetized, if the domains are not aligned it is not magnetized The smallest particle of an element is an atom. The atom has three parts: protons: positive electrical charge electrons: negative electrical charge neutrons: no electrical charge What is the center core of all atoms called? The smallest particle of an element is an atom. The atom has three parts: protons: positive electrical charge electrons: negative electrical charge neutrons: no electrical charge What is the center core of all atoms called?
