Electric Charge - Coggle Diagram
Electric Charge
Lightning and Grounding
Lightning and Thunder are created due to static electricity. The thundercloud creates charges which end up separated in the cloud. The negative charge of the cloud tries to connect with the ground, since it is positively charged. This connection creates lightning. These lightning split atoms generate sound. This sound is known as thunder.
Lightning strikes can cause a lot of serious problems. This is why grounding is used. Grounding is a strategy to use the Earth (a conductor) to reduce the damage of lightning strikes. The strategy consists of putting a conductor material in a really tall structure, and putting that material through the structure until it reaches the ground. Allowing the Earth to consume the lightning strike reducing or eliminating the damage done by it.
Electroscope
Electroscopes are machines used to detect electric charges. It is made so that a knob, a metal rob and metal leaves, get the electric charge, transport it and show if it is charged respectively. When an object charged touches the knob, the rob transport it and if it is charged the metal leaves separate.

Atoms and Charges
Matter is composed of atoms. These atoms are made of protons, neutrons and electrons. Protons have positive charge, neutrons have neutral charge and electrons have negative charge. Atoms that have an equal number of protons and electrons, have no charge, and are called electrically neutral.
Static Electricity
Electrons are arranged differently in each object. So objects can transfer electrons to another, changing the quantity of electrons per proton in both objects, making the object's charge to become either positive or negative. This excess of charge is known as Static Electricity.
The law of conservation of charge establishes that charge can not be created or destroyed only transferred. Usually the electrons are the ones transferred.

Forces and Fields
Charges create force, electric force. Equal charges repel and opposite charges attract each other. Just with charges, forces are reduced as both objects are moved farther apart.
Electric fields surround each electric charged object and exert force. Gravitational force is far more weaker than electrical force. There is more presence of gravitational force than electric force, because there are many objects with neutral charge. These forces are exerted in atoms.
