free particle Explanation: I'm quite sure this is what is meant. There could be particles which have fractional charge (quarks) but they are always bound. The charge is quantized for free (charged) particles. In Spanish it's "libre" so I guess it should be similar in Portuguese. Example sentence(s):

| Reference Reference information: The electromagnetic force is one of the four fundamental forces in physics. Electromagnetic force is caused by electric charge. Charge quantization is the principle that the charge of any free-standing object is an integer multiple of the elementary charge. By convention, the electric charge of a single electron is -1e which is minus 1.602 * 10 -19 Coulombs. It is the smallest unit for a negative charge carried by an isolated particle. The charge of a particle is only noticeable in the presence of a second charged particle, thus electric fields are usually determined using another, positive charge named test charge. https://homofaciens.de/technics-electrical-engineering-charg... Free-standing Not attached to or supported by another structure. ‘a free-standing cooker’ 1.1 Not relying on or linked to anything else; independent. ‘most nursing homes and free-standing therapeutic facilities are investor-owned’ https://en.oxforddictionaries.com/definition/free-standing Possible translations of 'free-standing' = isolated, single, individual |
