The total energy is the sum of the electron's kinetic energy and the potential energy coming from the electron-proton interaction. The kinetic energy is given by KE = 1/2 mv 2. This can be found by analyzing the force on the electron.
These things have the same size charge, but the sign is different. A proton has a charge of +e, while an electron has a charge of -e. Electrons and protons are not the only things that carry charge. Other particles (positrons, for example) also carry charge in multiples of the electronic charge. Those are not going to be discussed, for the most part, in this course, however.
