What else can I help you with?
What Elements in the same row are filling up the same energy level as you move from left to right?
Elements in the same row, or period, of the periodic table fill up the same energy level as you move from left to right. This is because elements in the same period have the same number of electron shells.
How would a proton's motion differ from the motion of an electron placed at the same point in the same electric field?
First of all, the forces they experience would be in exactly the opposite directions. Secondly, because the mass of the proton is greater, it would have a lower acceleration than the electron.
Do electrons from a battery reach the bulb before it lights?
No, electrons from a battery don't reach the bulb before it lights. An electric current is not simply a flow of electrons. Rather, an electron in a circuit will move only a short distance and then nudge another electron into motion, which will do the same thing with yet another electron. So while the current moves through the entire circuit, individual electrons do not unless it is left on for a very long time.
The differences between a series circuit and a parallel circuit?
In a series circuit, electrons flow through all the components one after another. If one fails (break), the whole circuit is no longer live. All the resistances are also added up in a series circuit. The current (measured in amps) is the same throughout the whole circuit. In a parallel circuit, electrons flow through smaller circuits all coming from the same source. The amperage is different in each circuit based on the resistance offered. The one wire running to all the smaller circuits has higher current than any of the small offset circuits. Removing one thing will not affect the other smaller circuits as electrons can still flow. Current will be affected, of course.
Why is the voltage the same in a parallel circuit?
This is due to Kirchoff's law. The total voltage around a closed loop must be zero.This is related to energy conservation. An electron (for example) needs a certain energy to go from point "A" to point "B", against the electrical forces (voltage, really). Voltage is defined as energy per unit charge. If the electron could, for example, go one way and gain an energy of 5 electron-volts (the energy an electron gains when going through a potential of 5 volts), then go another way and lose 4 electron-volts, this could be used to build a perpetuum mobile - therefore it isn't possible.
What Elements in the same row are filling up the same energy level as you move from left to right?
Elements in the same row, or period, of the periodic table fill up the same energy level as you move from left to right. This is because elements in the same period have the same number of electron shells.
Why does not it matter where you measure the current in a simple circuit?
The current measured at any point in a simple circuit will be the same because current is the measure of electron flow through a circuit. The current flowing through any branch of any circuit (or an entire simple circuit) will always be the same at any point.
What do the elements have the same number of as you move left to right?
electron shells
Do electrons from a battery reach a bulb before it light?

The circuit is a series circuit because?
The same current flows through both light bulbs.If one of the resistors run out of power,the whole circuit shuts down
Does an electron have the same speed as a proton?
Both electrons and protons can travel at different speeds. However, since a proton has about 1800 more mass than an electron, the same voltage will make an electron move faster than a proton.Both electrons and protons can travel at different speeds.

Can you shut off one appliance at a time on a parallel circuit?
Only if you install separate switches for each part of the circuit. The whole point of a parallel circuit - is that both parts of the circuit are controlled by the same switch.
As you move across a period elements have the same number of?
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
Why positive ions have more protons than electrons?
To conduct electricity we have to move electrons around in circuit. Metals have a large electron pool so battery mostly have electrolytes which imparts enough energy to electrons so that they can move around in the circuit. It not possible to single out protons out of the nucleus. Answer. There aren't. If the battery has a neutral charge there are the same number of each. Even if it is fully charged the positive terminal exactly balances the negative.
How magnetism is created by moving charges?
The whole point of magnetism IS moving charges. We have permanent magnets, because of the same electron "current" orientation, the same electron spin or any other moving charge. http://en.wikipedia.org/wiki/Electron_magnetic_dipole_moment
