Conduction
Being hit by a photon gives the electron increased energy. Higher energy electrons rise into another energy level. *Also when it releases a photon it drops to a lower energy level because it gives off energy.
Current A second condition needed in order for a current to flow is a path along which electrons can travel. Some materials are able to provide such a path, and others are not. Materials that permit a flow of electric current are said to be conductors. Those that block the flow of electric current are called nonconductors or insulators. The metal wire connecting the two battery poles in the example cited earlier provides a path for the movement of electrons from one pole of the battery to the other.
The movement of electrons from one place to another is Current.
Answer #2. Also, it could be called 'electricity'.
They don't. Energy imparted onto them does.
Electrons flow from one thing to another in a circuit. They are called a current when they flow. A circuit is a closed loop, it's made of stuff that can move the current.
Electricity.
Ionic Bonding
Excited state
valence electrons are the electrons in the outermost energy level
Valence electrons are the electrons in the outermost energy level.
Bonding occurs when atoms gain,lose,or share electrons in their outer energy level.
Electrons in the outermost principal energy level are called valence electrons.
Answer this question… The extra electrons begin to fill the next energy level.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Excited state
valence electrons are the electrons in the outermost energy level
Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Electrons:)
protons move to a higher energy level protons move to a lower energy level electrons move to a higher energy level electrons move to a lower energy level
128 electrons could fit in the 8th energy level.
It must absorb or give off energy
Three (3) electrons in this energy level.
Which energy level? There are several. With different numbers of electrons...
