In atoms and molecules that make up all materials, electrons are bound by attractive forces, magnitude of which depend on the electronic structure of the material. In the case of metals, this binding energy is rather small and if we supply an energy equal to this binding energy (also called, work function) the electrons can be set free.

In which layer of the sun is a huge supply of energy produced?
Energy in the form of light and heat is produced in the sun's core through nuclear fusion reactions. This energy then moves outwards through the radiative zone and convective zone before reaching the sun's surface (photosphere) and being emitted as sunlight.
What is the effect on an external power supply has on electrons?
it will probably bring more in to the party
What is the energy supply for photosynthesis?
The energy supply for photosynthesis is sunlight. Plants, algae, and some bacteria use the energy from sunlight to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis.
What is the energy source that pushes electrons around a circuit?
The energy source that pushes electrons around a circuit is typically a battery or a power supply. This energy source provides the necessary voltage difference for electrons to flow from the negative terminal to the positive terminal, creating an electric current.
What are the energy transfer in an electric fire?
In an electric fire, energy is transferred from the electricity supply to the heating element through the flow of electrons. The heating element then converts this electrical energy into heat energy, which radiates out into the room to provide warmth.
How can heat treatment change the properties of metal?
by heating metals we supply energy to the electrons in various energy levels and that makes the electrons go to the excited state from ground state. as kinetic energy is direct proportion to heat, the kinetic energy of the electrons increase as the heat increases.so the atoms try to move more freely and the inter molecular bonds get looser, so the the properties of metal get changed.
How do electrons transfer energy?
They don't. In the case of d.c., electrons move extremely slowly through a conductor, less than a millimetre per hour; in the case of a.c., they simply vibrate backwards and forwards. So electrons don't transfer energy from the supply to the load. Energy doesn't even pass through wires -it is transferred by a combination of the magnetic and electric fields, around the wire.
What part of the curcuit pushes the electrons?
The voltage source (such as a battery) is what provides the energy needed to push the electrons through the circuit. Electrons flow from the negative terminal (cathode) to the positive terminal (anode) of the voltage source in a closed circuit.
Where do the supply of electrons come from in photosynthesis?
The supply of electrons in photosynthesis comes from water molecules. This process, known as photolysis, occurs in the light-dependent reactions of photosynthesis. Water molecules are broken down into oxygen, protons, and electrons, with the electrons being used to replenish the electrons lost in the photosystem II reaction center.
How much Supply of Geothermal Energy is Left?
It is estimated that there is enough geothermal energy stored beneath the Earth's surface to provide power for billions of years. The amount of geothermal energy available for extraction depends on the specific location and technological advancements in accessing it.
Are there protrons netrons and electrons inside a battery?
There are protons, neutrons, and electrons inside everything that you can touch. If you provide a path for them outside the battery, electrons will flow from the battery's negative terminal to the positive one, and supply some energy on the way that you can use to run things or heat things with.
Why is the resistor designed in such a way that it oppose its flow of electrons?
A resistor determines the speed that electrical energy is spent, the power. Without it, the supply is spent immediately and cannot be stored.
