atom and electricity

1 atom and electricity matter and electrical charge discovery of electron atom and positive particles discovery of neutron
2 matter and electrical charge history of electricity greeks around 600 bc found that by rubbing a hard fossilized resin amber against a fur cloth it would attract particles of straw this strange effect remained a mystery for over 2000 years
3 william gilbert around 1600 in his book de magneta he introduced a new latin word electricity the word electricity comes from the greek elektron which means amber de magneta
4 benjamin franklin conducted many experiments on static electricity from 1746 1751 hes best remembered for the franklins kite experiment with lightning terms he invented are positive and negative electricity to charge meaning to store electricity
5 franklins kite experiment he attached a key to the string of the kite near his hand then let the kite fly the kite was struck by lightning and sparks flew from the key to his hand giving him a shock  this proved the theory that lightning was electrical in nature franklins kite experiment he attached a key to the string of the kite near his hand to conduct the electricity and create a charge then let the kite fly the kite was struck by lightning and sparks flew from the key to his hand giving him a shock  this proved the theory that lightning was electrical in nature httpwwwpbsorgbenfranklinexpshockinghtml
6 richman at saint petersburg also tried saint petersburg also at saint petersburg was as lucky lightning experiment and swedish scientist georg also tried franklins franklins lightning experiment was instantly killed not everyone was lucky as franklin tried franklins lightning as franklin swedish scientist georg richman everyone was as experiment and was georg richman at as lucky as and was instantly franklin swedish scientist
