When any conducting material is connected to provide a continuous path between the
two terminals of a battery, electric current flows through it. On the microscopic level,
electric current is really the flow of electrons, from the battery's negative terminal,
through the conducting path, to its positive terminal.
It depends on your definition of high energy. Electrons close to the nucleus have a high positive energy and will require a lot of energy to elevate them to higher orbitals. Electrons far away from the nucleus have the potential to give off a lot of energy falling to inner orbitals.
try using lithium batteries they work best in digital cameras
The latest Flip cameras can use battery packs or 2 AA batteries. Slide the lock for the battery compartment on the bottom of the camera to the unlocked position. The panel should then slide down and lift off allowing access to the battery compartment for replacing the batteries.
Why is it important that plants give off oxygen during photosynthesis
The intensity of the x-ray can be increased by the voltage going to the cathode which will increase the amount of electrons being given off through the vacuum and hitting the tungsten target which means more electrons hitting the target so more x-ray radiation being given off. You can also change how fine the beam is because if you have the beam of electrons focused on one area then the increase of the electrons hitting that one area will cause the increase in x-rays being given off instead of them being spread out over a large area.

NOTHING
all alkali metals give off only one electrons. However cesium will give off electron easily. (Francium is not considered generally as it is radioactive with very short half life period).
Yes, when charging hydrogen gas is released.
Metals, particularly the alkali metals- lithium, sodium, potassium, etc
When lead/ acid batteries are charged, they can give off hydrogen gas.
No it does not.
1) Electrons flow from a positive to a negative voltage source. 2) The path taken by the electrons through the circuit depends on the resistance of the various circuit elements. 3) Sensors attached to the circuit provide real world inputs and outputs. 4) All circuits are made using transistors. Transistors act like taps. Open the tap with a small amount of effort (a few electrons) allows a large volume of water (a large number of electrons) to flow. Analog circuits (e.g. Amplifiers) work by varying the amount of how open the tap is. Digital circuits (e.g. Computers) work by switching taps fully on or off.
conductivity
When electrons fall to a lower energy level, they give off energy in the form of light.
Calcium is a metal. Metals give away their electrons off to non-metals. So i would say when calcium is combining with another atom it wants to give away its electrons so it can be an ion.
Atoms give off (emit) electromagnetic waves by electrons dropping to lower orbit levels from higher levels of orbit.
