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.


What protein complex absorbs in energy that used to produce NADPH?

Photosystem 1


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.


Which element have 10 electrons and 10 neutrons?

Neon is the element with 10 electrons. Neon has 2 electrons in the K shell (or first energy level), and 8 electrons in the L shell (the second energy level).


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.


What is the second quantum number for one of the electrons in the 4p energy sublevel of bromine?

How many electrons does the N level of an atom hold?

K,L,M,NN is the fourth shell. It can hold a maximum of 32 electrons.2n2 is the maximum electrons for the energy level (n).


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.
