The world around us, and each one of us, is full of positive and negative charges. Electric circuits rely on the flow of charge, as does the human nervous system.
The symbol for charge is q or Q.
The MKS unit of charge is the coulomb (C).
Rank the electron, proton, and neutron based on their mass, from largest to smallest.
|Neutron||0||1.674 x 10-27 kg|
|Proton||+e||1.672 x 10-27 kg|
|Electron||-e||9.11 x 10-31 kg|
Other elementary particles also carry charge.
