P2.1 Static electricity

- All atoms contain electrically charged particles called protons and electrons. -Protons have a posotive charge and are found in the nucleus of atoms.  - the elctrons move around the nuclus of the elctron. - Atom has no overall charge = posotive charges on the protons, balanced by negative charges on electrons.  -nucleus also contains neutrons, which have no charge.  - An insulator can be charged by friciton, through the transfer of electrons. - the material gaining electrons becomes negativley charged. material loosing electrons is left with and equal posotive charge.  -like charges repel, unlike charges attract. -balloon has negative charge, when touched with the wall the posotive charge is left behind (the induced charge) attracts the neg charge on the balloon. electrons in the wall repel and move away.  - when you rub an acetate rod with cloth, some electrons in the acetate move onto the cloth. when you rub poluthene rod, some of the electrons in the cloth move onto the polythene. the acetate has now become posotive and the cloth has become and equal negative charge.

P2.1 Static electricity

- All atoms contain electrically charged particles called protons and electrons.

-Protons have a posotive charge and are found in the nucleus of atoms. 

- the elctrons move around the nuclus of the elctron.

- Atom has no overall charge = posotive charges on the protons, balanced by negative charges on electrons. 

-nucleus also contains neutrons, which have no charge. 

- An insulator can be charged by friciton, through the transfer of electrons.

- the material gaining electrons becomes negativley charged. material loosing electrons is left with and equal posotive charge

-like charges repel, unlike charges attract.
