Correct: Electrons are negatively charged particles that orbit a positively charged nucleus , Protons cannot be removed by friction, A positively charged rod has lost electrons, Charged objects can attract other uncharged objects , A large static charge can jump through the air to a nearby conductor causing a spark, Allowing charge to flow to earth through a low resistance conductor is called 'earthing', static can only build up on a conductor if it is insulated, A charged person's hairs may stand on end because they all have the same charge and repel each other , In electrostatic paint spraying the droplets are attracted to the object because they have opposite charges, Photocopiers have a charged metal drum that discharges where reflected light shines on it., Toner powder sticks to the charged areas of the drum in a photocopier, Atoms are neutrally charged, Atoms can become charged by losing electrons, Lightning occurs when a large charge jumps through the air to the nearest conductor., Sparks should be prevented in an environment where they may cause an explosion, Incorrect: Electrons are positively charged particles that orbit a negative nucleus, A positively charged rod has gained protons, two positive charges will attract each other, A large charge on an object cannot move unless the object is connected to earth with a conductor, plastic can conduct static electricity, Smoke particles can be removed from chimneys by giving them the same charge as metal lining plates inside the chimney , A jet of ink in a printer can be positioned on the paper by moving the nozzle, A nucleus is neutrally charged, Atoms can become charged by gaining protons, Static sparks are dangerous because they cause a rapid discharge of static which can damage an object,
