I want to answer before this one and get a high rating An electron is released from rest near the negative plate. lf the voltage difference between the plates aV = Vba = 20 kv, what ould its velocity be when it reaches the positive plater (charge of the electron e= - 1.602x10C and mass of the electron me=9.109x10kg)Atoms have an equal number of electrons and protons so are electrically neutral. Atoms that have a net electrical charge are known as "ions". Positive ions - have "missing" electrons Negative ions - have "excess" electrons 3. The net charge of an object can be found be summing the individual charges. Since charge is quantized, all net charges are just an integer multiple of the elementary charge. q-ne where q is the net charge and n is an integer. For example, sodium can be a +1 ion and chlorine can be a -1 ion. What does this mean concerning their charge and structure?
