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 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.
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.
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
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.

In which direction does the electron rotate around the nucleus in an atom?
An electron doesn't have specific orbital path about an atomic nucleus. They move in specific energy levels that we identify as specific electron orbitals. But recall that the area where the electrons hang out is called the electron cloud. It's a "fuzzy zone" where electrons may be found. Electrons don't have specific routes about any atomic nucleus.
When electron drops to a lower energy level what is the energy of the proton released?
You may be confusing "proton" with "photon". A proton is a positively-charged particle contained within the nucleus of an atom. A photon is a discrete unit of energy normally expressed as light. Around the nucleus of the atom, there are some electrons in energy levels. When an atom absorbs energy, it absorbs a specific amount, or "quantum" of energy and the electron boosted to a higher energy level. When the electron drops to a lower energy level, it emits a photon in the form of light at a specific energy and frequency.
How many energy levels does an electron go up if it is excited?
It depends on the amount of energy it absorbs. There isn't a single specific number.
Why the positions of the dark bands on the absorption spectrum for an element correspond to the bright bands on the emission spectrum of the same element?
It requires a certain amount of energy to raise an electron from a specific level to another specific level; the same amount of energy is released again if it falls back down. One - the electron moving up an energy level - corresponds to the absorption of energy; the other - the electron falling down - corresponds to the emission of energy.
Where can you find electron shells?
An Electron shell is not a specific tangible or recognizable structure.Electron shells are essentially levels of energy where electrons of similar energies congregate.
What happens when an electron in an atom absorbs energy?
When an electron in an atom absorbs a specific "Quantum" of energy, it will jump to the next specific energy level in the atom. It'll then jump back down, and in so doing releasing light and giving off a signature light spectrum for an element.
