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.
How is kinetic and potential energy involved when electrons move through a closed path?
When electrons move through a closed path, they possess kinetic energy due to their motion. As they move against an electric field, they also have potential energy, which is converted into kinetic energy as they move. This interplay between kinetic and potential energy is essential for the flow of electrons in a closed circuit.
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.
What is the Measure of the energy available to move electrons or potential difference?
potential energy
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.
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.
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.
Do neutrons have more energy than electrons?
No, Neutrons are nuetral so they do not move in different energy levels. Only Electrons do.

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

Atoms may emit light energy when?
Atoms may emit light energy when they transition from a higher energy level to a lower energy level. This release of energy produces light of specific wavelengths, creating an emission spectrum unique to each element.

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.
What are the energy levels of an atom occupied by?
An atom's energy levels are occupied by electrons. Electrons occupy the energy levels, or electron shells, in order of increasing energy. The lowest energy level is filled first before electrons move to higher 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.
