Answer: 37 protons, 48 neutrons, and 36 electrons.
Explanation: I assume "Revision" is Rubidium. It is atomic number 37, so it has 37 protons. It's atomic mass is 85, so it has an average of (85-37) = 48 neutrons. It has a charge of +1, so one electron of the original 37 has left.
Answer:
B: All of the choices!
Explanation:
Choice 1: Simply, there is no current without voltage, so it DOES cause current.
Choice 3: Voltage DOES push free electrons around a circuit. Without it, free electrons will move around between atoms, but randomly, so they wouldn't be much use.
Choice 4: Voltage IS measured in volts, so this option is true as well.
Choice 2: Voltage is all of those answers, so it is true! :D
Hope i helped! :]
There are two electrons in 4s and 6 in 3d. When you lose 3 electrons, you will be left with an ion of 3+ charge!
