There are two types of electrical charges. Positive and negative. These are decided by the natural balance of the atoms they involve, with protons being positive, and electrons being negative. So a negative charge would be an excess of electrons, and a positive charge would be a deficiencies of electrons. This un-conventional theory.
In electronics, they say a positive charge is an excess of electrons; and a negative charge is a deficiencies.
I took this definition from Wikipedia.
Formal definitionMore abstractly, a charge is any generator of a continuous symmetry of the physical system under study. When a physical system has a symmetry of some sort, Noether's theoremimplies the existence of a conserved current. The thing that "flows" in the current is the "charge", the charge is the generator of the (local) symmetry group. This charge is sometimes called the Noether charge.
Thus, for example, the electric charge is the generator of the U(1) symmetry of electromagnetism. The conserved current is the electric current.
In the case of local, dynamical symmetries, associated with every charge is a gauge field; when quantized, the gauge field becomes a gauge boson. The charges of the theory "radiate" the gauge field. Thus, for example, the gauge field of electromagnetism is the electromagnetic field; and the gauge boson is the photon.
Sometimes, the word "charge" is used as a synonym for "generator" in referring to the generator of the symmetry. More precisely, when the symmetry group is a Lie group, then the charges are understood to correspond to the root system of the Lie group; the discretenessof the root system accounting for the quantization of the charge.
So what it's saying is, any system that has the ability, or symmetry, that separates some things from their nature state, and keep them there; is a charge. So there can be many different charges. But in electricity, only two,

What are the two electric charges?
There are two types of charges: positive charges and negative charges. Positive charges are immobile, and are found inside the nuclei of atoms as Protons. Negative charges can be mobile, and have the source of electrons. These orbit the nuclei of atoms, and can be stripped from the atoms to be used as mobile charged through conductors, such as electricity moving through wires.
What the unlike charges?
the unlike charges are those which attract each other
What are two types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils
Does coulombs law predict the attraction between two unlike charges?
yes
What do Electrical forces between charges depend on?
Electrical force b/w two charges is given by Coulomb's law. It states that the force 'F' b/w two charges 'q1' & 'q2' separated by a distance 'r' is directly propotional to the product of magnitude of two charges & inversely propotional to square of distance b/w them i.e; F ¤ q1q2/r^2 => F = Kq1q2/r^2 where K = 1/4 pi epsilon nought = 9 *10^9 N m^2/C^2 is called dielectric constant of the medium and epsilon nought =8.854*10^-12 C^2/N m^2 is called absolute permitivity of free space. If the charges are in medium, then epsilon nought is replaced by epsilon.
How did they know that there was only two types of charges?
The observation of attraction between opposite charges and repulsion between like charges led to the conclusion that there are only two types of charges: positive and negative. Through experiments and observations, scientists determined that all electrical phenomena can be explained by the presence of these two types of charges.
What are two types of electric charge?
The two types of electric charge are positive and negative. Positive charges repel each other, as do negative charges, while opposite charges attract each other.
How many types of electrostatic charges have been discovered?
There are two types of the electrostatic charges that have been discovered. The positive and the negative charge. There is also the neutral charges.
How many types of charge have been discovered?
There are two types of the electrostatic charges that have been discovered. The positive and the negative charge. There is also the neutral charges.
Do ions posses charges?
Yes, ions are charged molecules by definition. There are two types cations (with positive charges) and anions (with negative charges).
What are the 2 types of electric charges?
The two types of electric charges are positive and negative. Positive charges repel each other, as do negative charges, while positive and negative charges attract each other.
What are different types of charges?
the different types of charges are positive and negative charges
What is the difference of the 3 types of charges?
what are the 3 types of charges
How many types of camels are there?
There are two species/types named "Dromedary" and "Arabian".
What are the two electric charges?
There are two types of charges: positive charges and negative charges. Positive charges are immobile, and are found inside the nuclei of atoms as Protons. Negative charges can be mobile, and have the source of electrons. These orbit the nuclei of atoms, and can be stripped from the atoms to be used as mobile charged through conductors, such as electricity moving through wires.
What two types of forces can result from electric charges?
Electrostatic force and magnetic force.
How do the two types of electric charges interact?
Opposite charges attract each other, while like charges repel each other. The interaction between two charges follows Coulomb's law, which states that the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
