Give three properties of electric charge.

$$Basic\ properties\ of\ electric\ charge:$$

$$Addivity\ of\ charges$$
Charges are additive in nature means they are like scalars and can be added directly. For an example, consider a system which consists of two charges namely $$q_1$$ and $$q_2$$. Now we wish to find the total charge of the system. The total charge of the system will be the algebraic sum of $$q_1$$ and $$q_2$$ i.e. $$q_1+ q_2$$.
$$Conservation\ of\ Charge$$
The charge is a conserved quantity which means charge can neither be created nor be destroyed but can be transferred from one body to another by certain methods like conduction and induction.
$$Quantization\ of\ charge$$
Quantization of charge means that charge is a quantized quantity and is expressed as integral multiples of the basic unit of charge (e charge on one electron). Suppose charge on a body is q, then it can be written as $$q = ne$$,where n is an integer like 1, 2, 3, -5 etc.
