What is the excited state selenium?
Excited state selenium refers to selenium atoms or ions that have absorbed energy, causing their electrons to move to higher energy levels. This temporary configuration is unstable, and the electrons will eventually return to their original energy levels, releasing the absorbed energy as light. This process is the basis for selenium's use in photovoltaic cells and other light-sensitive technologies.
Absorption of light by atoms of an element occurs when photons are?
Absorption of light by atoms of an element occurs when photons of light with energy levels matching the energy levels of the electrons in the atom are absorbed. This causes the electrons to move to higher energy levels, and the atom becomes excited, leading to the absorption of light.
When electrons absorbs energy they exist for a short time higher energy level. These electrons are said to be?
"Excited", or in an "excited state".
How is light energy is absorbed and dissipated by a pigment?
Light energy is absorbed by pigments through specific wavelengths that match the energy levels of their electrons. When light photons strike a pigment molecule, electrons are excited to a higher energy state. This absorbed energy can then be dissipated as heat, re-emitted as light (fluorescence), or used in biochemical processes, such as photosynthesis. The efficiency of these processes depends on the pigment's structure and the surrounding environment.
What event accompanies energy absorption by chlorophyll or other pigment molecules of the antenna complex?
The event that accompanies energy absorption by chlorophyll or other pigment molecules of the antenna complex is the excitation of electrons. When light energy is absorbed by the pigment molecules, their electrons get excited to a higher energy state. This excited state is essential for the subsequent transfer of energy to the reaction center of the photosystem for further processing.
The state of matter in which electrons have absorbed energy is called?
Excited Electrons
State in which electrons have jumped to a higher energy level?
state in which electrons have absorbed energy and "jumped" to a higher energy level
When electrons of an excited atom falls back to lower levels there is an emission of energy that produces what?
The electrons emit photons of light equal in energy to the energy that was absorbed.
An atom is in an excited state when it has its lowest energy?
No, when an atom is in an excited state, its electrons have gained energy, and they proceed to lose it when they fall back into their normal energy levels
What does it mean when the electrons are excited?
When electrons are excited, they absorb energy and move to higher energy levels. This can happen through various processes like heat, light, or electrical energy. The excited state is temporary, and electrons will eventually return to their original energy levels, releasing the absorbed energy in the form of light or heat.
A state in which an atom has more energy than it does at its ground state?
An atom is in an excited state when it has absorbed energy, causing its electrons to move to higher energy levels. These excited electrons are unstable and eventually return to their ground state by emitting energy in the form of light or heat.
Which is the highest energy state?
The highest energy state is the excited state, where an atom or molecule has absorbed energy and its electrons are at higher energy levels than their ground state. This state is temporary and unstable, as the electrons will eventually return to their ground state and release the absorbed energy.
When sunlight excites electrons in chlorophyll how do electrons change?
As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.
When sunlight excites electrons in the chlorophyll how do the electrons changes?
As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.
Where do electrons get there energy from photostem 2?
Electrons in photosystem II get their energy from sunlight. When photons from sunlight are absorbed by the chlorophyll molecules in the photosystem, the energy is transferred to electrons, allowing them to become excited and drive the process of photosynthesis.
How is energy absorbed?
Energy can be absorbed through various processes depending on the type of energy. For example, in the case of electromagnetic radiation, such as light, energy is absorbed when photons are absorbed by molecules, causing their electrons to be excited to higher energy levels. In the case of mechanical energy, absorption can occur through processes like friction and deformation of materials.
