Electric charge is quantized using this the electric charge of a particle that lost 5×10^13 electron equal?​

Quantization.

Explanation:

Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge. Thus, an object's charge can be exactly 0 e, or exactly 1 e, −1 e, 2 e, etc., but not, say, 12 e, or −3.8 e, etc.

if they have a finite resultant
