Why it is considered as the energy of an electron is quantised?
Electrons orbit the nucleus of an atom in specific orbitals, a specific distance from the nucleus of the atom. A specific quanta of energy will knock the electron into a higher orbital. When the electron falls back into the lower orbital, it will give off that same specific quanta of energy. That is why lasers work.
What happens to electrons when pigments in photo-systems 2 absorb light?
Light or photons are little packets of energy. When this energy is absorbed by an electron it boots the electrons energy and the electron jumps to a higher orbital shell position (which must be vacant of its electron). The electron can only do this when the energy needed for the jump and the energy in the incoming photon match. Thus specific colours of light are absorbed depending on the element present.
When an electron drops to a lower energy level what is the energy of the photon released?
The energy of the photon is the same as the energy lost by the electron
Does the energy of an electron vary depend upon which energy level it occupys?
Yes, the energy of an electron does vary depending on which energy level it occupies. Electrons in higher energy levels have more energy than those in lower energy levels. The energy of an electron is quantized and can only take on specific values corresponding to the energy levels of the atom.
What causes an electron to change energy levels within an atom?
An electron changes energy levels within an atom when it absorbs or emits a specific amount of energy, typically in the form of light or heat. This process is known as electron excitation or de-excitation.
An electron jumps to a new energy level when?
An electron jumps to a new energy level when it absorbs or emits a specific amount of energy in the form of a photon. This energy change causes the electron to move to a higher or lower energy level based on the difference between the initial and final energy states.
According the the Bohr model of an atom the single electron of a hydrogen atom circles the nucleus?
According to the Bohr model, the single electron of a hydrogen atom moves in circular orbits around the nucleus at specific energy levels. The electron can only occupy certain quantized energy levels and emits energy when transitioning between levels.
When sunlight excites electrons how do the electrons change?
Depending on the energy (frequency) of the specific photon hitting the electron, one of three events happens: nothing, the electron is excited, or the electron leaves the atom. If the energy of the photon very high, the electron can absorb the energy and escape the nucleus' pull. This is called ionization. If the energy of the photon lines up with the energy spacing in the atoms energy levels, the electron will move to a higher energy state, becoming excited. The electron then returns to its original energy level, releasing the energy as light. If the energy of the photon does not fall into one of these categories, the electron does not interact with it. In terms of actually changing the electron, it only changes in energy, not any other property.
Why are electron shells called energy levels?
Electron shells are called energy levels because electrons within them have specific energy values associated with their position in the atom. The farther an electron is from the nucleus, the higher its energy level. Electrons can move between these energy levels by gaining or losing energy.
How does the transition show that the position of the electron is quantized?
The transition of an electron between energy levels in an atom shows that the position of the electron is quantized because only specific energy levels are allowed for the electron to occupy. This means that the electron can only exist at certain distances from the nucleus, corresponding to discrete energy levels, and cannot be found in between these levels.
When an electron moves from a higher energy level to a lower energy level the atom commonly?
The electron moving from a lower to a higher energy level equates to moving from a specific orbit 'r' to a specific orbit 'rr' that is farther from the nucleus.
Will an electron excite if it is given energy that will allow it to exist in between two energy levels?
Will an electron excite if it is given energy that will allow it to exist in between two energy levels? No An electron can only exist in specific energy levels. Giving an electron more energy can make it escape from the attraction of the protons completely and the atom now has 1 less electron and is a +1 ion. Have you seen an electron discharge tube? If I turn up the power, the tube will become brighter, but the color will not change. The color of light is the product of the electron returning from the excited state to its ground state.
