What is the name for the unit that measures energy available to move electrons?

No. Current has nothing to do with available energy. Current is strictly the size of
the flow ... the number of electrons that pass a window in the wire each second.

The unit that measures energy available to move electrons is called electron volt (eV). It is commonly used in physics and chemistry to describe the energy levels of electrons in atoms and molecules.

Kilo is 1000 and Mega is 1000,000.

Why does a semiconductor have fewer electrons than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
When an atom absorbs enough energy electrons move to an orbital?
When an atom absorbs energy, electrons can move to higher energy orbitals further from the nucleus. This process is known as excitation, and it can lead to the temporary promotion of electrons to higher energy levels until they eventually fall back to their original positions, releasing the absorbed energy as light.
Compare the outermost electrons of an atom with the inner electrons of an atom in terms of energy.?
The outermost electrons of an atom, also known as valence electrons, have higher energy levels compared to the inner electrons. Valence electrons are involved in chemical bonding and interactions with other atoms, while inner electrons are more tightly bound to the nucleus and have lower energy levels.
Can atoms change energy levels?
Yes, atoms can change energy levels by absorbing or emitting energy in the form of light or heat. This process is known as electronic transitions. When an atom absorbs energy, its electrons move to higher energy levels, and when it emits energy, its electrons move to lower energy levels.
When electrons move closer to the nucleus is energy lost or gained?
When electrons move closer to the nucleus, they release energy and lose energy overall. This energy is typically emitted in the form of light or heat.
What is the Measure of the energy available to move electrons or potential difference?
potential energy
Atoms may emit light energy when?
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
Do electrons release energy when they move to a higher energy level?
Yes, electrons release energy when they move to a lower energy level. When electrons absorb energy and move to a higher energy level, they are in an excited state. When they return to a lower energy level, they release energy in the form of light or heat.

Positive ions and electrons can flow in a a solution but only electrons can flow in wires. What causes the electrons to move?
In wires, the movement of electrons is driven by an electric field created by a voltage source. This electric field exerts a force on the electrons, causing them to move. In contrast, in a solution, positive ions and electrons can move because of the flow of electric current through the solution.
Do neutrons have more energy than electrons?
No, Neutrons are nuetral so they do not move in different energy levels. Only Electrons do.
Is it true electrons gain energy as they move down the chain?
No. Electrons gain energy as they move up the chain, i.e. in more outer shells.
What is the emission of electrons from a metals surface?
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface
How does an electron move when it releases energy?
Electrons move to a lower energetic state within an atom or molecule when they release energy.
What may move between energy levels When an atom gains or loses energy?
electrons
Is it true that energy is used to force electrons to move to higher energy levels?
yes
