Electrical phenomena and electrical nature of matter

Electrification phenomena occur by the electrical charge (property of the matter).

The amount of electric charge (Q) has as a unit the coulomb (C)

1. Electrical charges types: + and -
2. A body is electrically neutral when the number of electrical charges + (protons) is equal to the number of electrical charges – (electrons)
3. A body can only acquire electrical charges when it gains or loses negative charges (electrons)
4. An electrically neutral body that loses negative electrical charges remains charged positively and one who gains negative electrical charges becomes negatively charged.
5. Two bodies with electrical charges of the same type are repelled, while if they have electrical charges of different types, they are attracted.

Mostly an atom is neutral, which means that atom has the same protons and electrons number. If an atom wins or loses electrons, it becomes an ion. If an atom wins electrons it becomes an ion called anion. In contrast, if an atom loses electrons, it becomes an ion called cation.
