- Static Electricity
- Atoms have a central nucleus with electrons moving round it
- nucleus is tiny but makes up most of atom mass
- contains protons and neutrons - overall positive charge
- rest of atom mostly negative space
- negative electrons move around the outside fast - give overall size but have no mass
- nucleus is tiny but makes up most of atom mass
- Build up of static caused by friction
- 1 - two insulating materials are rubbed together; electrons scrap off on and dumped on other
- 2 - leave a positive static charge on one and negative on the other
- 3 - only electrons can move not protons; way electrons are transferred depends on two materials involved
- classic examples - polythene and acetate rods being rubbed with a cloth duster
- Atoms have a central nucleus with electrons moving round it
