In Photosystem I (PSI), electrons gain energy primarily through the absorption of light by chlorophyll and other pigments. When photons are absorbed, they excite electrons to a higher energy state. This process occurs in the reaction center of PSI, where the excited electrons are then transferred through a series of proteins in the electron transport chain, ultimately leading to the reduction of NADP+ to NADPH. This energized electron transfer is crucial for the photosynthesis process, as it helps convert light energy into chemical energy.

Where do electrons come from and how it gains energy during the light reaction?
They come from Photosystem ll. Photosystem ll gets them by ripping the electrons off of water by a process called photolysis. Electrons gain energy first in Photosystem ll, then later in photosystem l, through the absorption of energy from light.
Where do electrons get their energy in photosynthesis l?
In photosynthesis, electrons gain their energy from sunlight, which is absorbed by chlorophyll and other pigments in plant cells. This energy excites the electrons, raising them to a higher energy state. The energized electrons then move through the electron transport chain, facilitating the conversion of light energy into chemical energy, ultimately leading to the production of glucose and oxygen.
What is the maximum number of electron in the second princple energy level?
If you are saying about L-shell then it has the capacity of 8 electrons. The l-shell consists of 2s and 2p orbitals which are capable of holding 2 and 6 electrons respectively.
How many electrons are there in the L shell of neon?
2 electrons in the K shell and 8 electrons in the L shell
How many electrons in n4 l3?
In the notation ( n=4 ) and ( l=3 ), the principal quantum number ( n ) indicates the energy level, and ( l=3 ) corresponds to the f subshell. The maximum number of electrons in a subshell is given by the formula ( 2(2l + 1) ). For ( l=3 ), this results in ( 2(2 \times 3 + 1) = 2(7) = 14 ) electrons. Thus, there can be a maximum of 14 electrons in the ( n=4, l=3 ) subshell.

What is a role of photosytem l in the light reactions?
It is placed as second photosystem in the light reactions of plants, algae and some bacteria. It is an integral membarne protein complex. It functioning the electron transfer from plastocyanin to ferredoxin. Like PSII, PSI also uses light energy to excite electrons.
What is the second quantum number for the electrons in the 4p energy sublevel of bromine?
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
How is the valency of an atom determined?
by the number of electrons lost or gain by the atom to complete it's outer most energy level example : magnesium's atomic number is 12 so the electronic configuration in the 7 energy levels K L M N O P & Q will be 2-8-2 so the atom tends to loss 2 electrons so the valency of Magnesium is 2. note: in the outer most energy level if the electrons are 1-2-3 the atom tends to loss them , 4 the atom tends to share , 5-6-7 the atom tends to gain IN ORDER TO complete the outer most energy level with 8 electrons except when the outer most energy level is K it needs only 2 electrons to be completed.
How many energy levels are occupied in an atom of oxygen?
