Where does the energy to excite electrons come from?

Electrons get excited when they absorb photons or particles of light. There is specific energy difference between different shells of electrons. So an electron if given the required amount of energy to jump from its ground state to a higher state, will get excited.

Why electron in carbon gets excited though it needs energy?

Bonding in any element will take place with only the valence shell electrons. The valence shell electrons are found in the incomplete, outermost shell. For this reason, carbon will form an excited state by promoting one of its 2s electrons into its empty 2p orbital and hybridize from the excited state.

What is the excited state of carbon?

An excited state electron configuration of carbon is 1s2 2s1 2p3.

What is the source of energy for excitation of electron in orbital hybridization?

The hybrid orbitals thus formed by the mixing of atomic orbitals are more stable and have less energy than the atomic orbitals. the excess amount of energy is released in stabilization of hybrid orbitals and is used in excitation of one electron from low energy 2s orbital to high energy 2pz orbital.

How do photons excite electrons?

Photons are electromagnetic waves that propagate in wave packet. Those wave packet carry a defined quantized amount of energy. When a photon interact with an electron it will give away its energy to the electron. The electron will have more energy and hence a larger velocity.

How does carbon gain energy for excitation of electron from 2s to 2p orbital?

In the VSEPR model, the carbon atom has four electron pairs, and the molecular geometry is tetrahedral. B Carbon has a 2s22p2 valence electron configuration. By hybridizing its 2s and 2p orbitals, it can form four sp3 hybridized orbitals that are equal in energy.

Where does the energy of an atom come from?

Most of the energy that can be found in an atom is in the form of the nuclear mass. The nucleus of an atom contains protons and neutrons, which are held together by the strong nuclear force. If that force were to be disrupted, the nucleus would tear apart and release a portion of its mass as energy.
