: A [[material]] that gains [[electron]]s becomes [[Negative Charge|negatively charged]].
: A [[material]] which loses [[electron]]s becomes [[Positive Charge|positively charged]].
: Once a [[material]] has become '''statically charged''' it will [[repel]] anything with the same [[Electrical Charge|charge]] and [[attract]] anything with the opposite [[Electrical Charge|charge]]. This happens due to the [[Electrostatic Force|electrostatic force]].: [[Lightning]] is caused by a build up of '''static electricity''' in which clouds gain [[electron]]s from the ground. The [[Electrical Charge|charge]] builds up until the [[Electrostatic Force|electrostatic force]] is so large that the [[electron]]s are able to jump to the ground as a bolt of [[lightning]].

For certain [[material]]s [[electron]]s can be transferred from one [[material]] to the other by [[friction]].: A [[material]] that gains [[electron]]s becomes [[Negative Charge|negatively charged]].: A [[material]] which loses [[electron]]s becomes [[Positive Charge|positively charged]].: Once a [[material]] has become '''statically charged''' it will [[repel]] anything with the same [[Electrical Charge|charge]] and [[attract]] anything with the opposite [[Electrical Charge|charge]].
