What is the charge of electron?
I am looking at a table about inside an atom, it shows a charge of proton is +1.60*10^-19c, neutron with the charge of 0 and electron charge of -1.60*10^-19C. However, when I have to work out the specific charge of electron so it becomes +1.60*10^-19C.......Why is that negative becomes positive when we have to work out the specific charge of electron? here is the example "The electron has a charge of +1.60*10^-19C and a mass of 9.11*10^-31kg. Its specific charge is therefore 1.76*10^11Ckg^-1"....Please help...thank you....

In the example you give, the electron doesn't have positive charge. The MAGNITUDE of its (negative) charge is 1.60*10^-19C - that is the absolute value of its charge. To calculate the "specific charge" you take the absolute value of the charge, 1.60*10^-19C, and divide by the mass, 9.11*10^-31kg. The result is 1.76*10^11Ckg^-1.

Electronic charge is always negative. There must be an error in the question...by the way are your references over the internet?
