Electric charges
Protons are positive and electrons are negative. The amount of positive charge of a proton equals the amount of negative charge of an electron. A particle with equal amounts of positive charge and negative charge is electrically neutral Electrically neutral atoms make up all objects, therefore, objects are normally electrically neutral
An object is electrically charged when it has an unbalanced amount of positive charge or negative charge.
Positively Charged An object that has lost one or more electrons as it comes in contact with another object has an unbalanced electric charge. An object that has lost electrons has more protons than electrons. Thus, the object has more positive charge than negative charge. The object is positively charged.
Negatively Charged An object that gains one or more electrons also has an unbalanced electric charge. An object that has gained electrons has more electrons than protons. Thus, the object has more negative charge than positive charge. The object is negatively charged.

Lightning
Lightning is a form of direct current (DC) produced by static electricity in clouds.
The static is formed when air molecules move past each other (just like clothes in a dryer).
The negative charges group at the bottom of the cloud and transfer electrons to the ground, which has taken on a positive charge.

Electric discharge
The loss of an unbalanced electric charge is an electric discharge. Example: A sudden electric discharge through the gas-filled tube of the camera flash causes the gas to produce a burst of light.
Electric force
The force is a push or a pull depends on the types of charge on the objects, as shown in the figure. If both objects are positively charged or if both objects are negatively charged, the two objects push each other away. In other words, objects with the same type of charge repel each other.
If one object is positively charged and the other object is negatively charged, the two objects pull each other together. In other words, objects with opposite types of electric charge attract each other.
