Electrons have a charge of -1. Neutrons are neutral ... Ions are attracted to other atoms and molecules. If your atom is too ionized, it will likely zip away from you and attach itself to a ...

He sent an electrical charge through a flask of a chemical solution ... there must have been a crucial step that turned atoms into organisms, but they still don't know what it is.

This flow of electric charge is called a current ... Inside the plastic, all the electrons are tightly bound to the atoms, so the charges cannot move very far, and no current can flow.

The buildup of static charge often occurs due to friction. At a microscopic level, even smooth surfaces are rough and irregular.

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms ... is rubbed on the skin, electrons from the skin are transferred to the plastic giving the ...

Why do different materials vary in their properties, such as electrical conductivity ... s discovery that atoms contain a central ‘nucleus’ of densely packed positive charge.
