Cards in this deck (9)
- 1AtomsAll substances are made of atoms. An atom is usually electrically neutral (has no electrical charge). However, in each atom there are even smaller particles called “Electrons”.
- 2ElectronsElectrons have a negative charge. Therefore, if an atom gains an electron, it can become negatively charged. If it loses an electron, it becomes positively charged.
- 3ProtonA Proton is a subatomic particle found in the nucleus of every atom.
The particle has a positive electrical charge, so it is equal and opposite to the Electron.
- 4NeutronNeutrons are particles in an atom that have a neutral charge.
- 5Neutral ChargeIf an atom has a neutral charge, it means that it has the same amount of protons and electrons.
- 6Negative ChargeIf an atom has a negative charge, it means that it has more electrons than protons.
- 7Positive ChargeIf an atom has a positive charge, it means that it has less electrons than protons.
- 8Static ElectricityWhen you rub two different materials against each other, they become electrically charged.
This only works for electrically insulated objects. Materials such as metals (which conduct electricity) cannot be electrically charged.
- 9Movement of ElectronsIf you rub an Acetate Plastic Rod with a Duster, the electrons from the plastic rod goes towards the atoms in the duster. Because of this, the duster becomes negatively charged, and the plastic rod becomes positively charged (due to it’s atoms losing electrons).
