What is the charge on a proton? And on a neutron?

OpenStudy (anonymous):

i got it , 0

OpenStudy (jamesj):

Nope. The charge on a proton is +1 The charge on a neutron is 0 (that's why it's called neutron, from neutral) The charge on an electron is -1 Now redo your calculation.

OpenStudy (anonymous):
