Where do the electrons go in the common wire?
the electrons don't actually go anywhere, they move in a circular mode... the electrons bounce from one atom to another so that there is always balance... as soon as a valence electron moves to another atom another electron replaces the one just lost... ...
What does the light reaction require that the dark reaction does not?
the light reaction requires energy from the sun in the form of photons. these photons excite the electrons in photosystem II and results in the electrons passing through a series of redox reactions (creating a proton gradient that through chemiosmosis turns ADP into ATP) and replaces the missing electrons of photosystem I. then when photons hit photosystem II the electrons are re-energized and go through the reaction to reach NADP+ and though NADP+ reductase are accepted by the newly formed NADPH. so in...

What happens to the water absorbed by plants?
The main purpose of the water taken in by plants is to be '' cracked '' for the electrons needed to replace the electrons excited when photons strike the chlorophyll pigment and they are excited to a higher level and enter a photosystem. The plant '' cracks '' the water and replaces these lost electrons and the system keeps moving. The secondary purpose, but still very important, is that plants need to keep turgid and need water pressure against the cell wall to...

Why is the mobility of electrons greater than holes?
In an intrinsic semiconductor, a few electrons get thermally excited and break from their valence bond to become a free electron. This leaves behind a vacancy in its place called 'hole'. In a P-type semiconductor, B with 3 electrons replaces a Si atom with 4 electrons in the lattice. 3 covalent bonds are formed by B with 3 neighbouring Si. But there is a deficiency of one electron in B for bonding with the 4th Si. This deficiency/vacancy is called a hole. When an...

Why 2nd and 6th group elelments are not used for doping of semiconductors?
III and V group atoms are used for doping in column IV materials. III and V relate to the number of valence electrons that are available for bonding. Silicon, which is a column IV material, is usually in a bonding form with 4 other Si atoms. In this bonding scheme, valence electrons are shared and the "outer shell" of 8 electrons is complete. In doping, an atom replaces one of the Silicon atoms. A column V atom, such as Phosphorous, can replace...

What is sp3 hybridization of carbon?
sp3 hybridization of carbon is a description of the electronic state of electrons in a single covalent bond of carbon to another atom of carbon. This is an electronic state that does not exist in an isolated carbon atom, but it is the lowest energy state for bonding electrons between two singly bonded carbon atoms. The designation "sp3" means that this electron state replaces the normal s and p level electrons in the valence shell of an isolated carbon atom and that...

Why it is necessory to assume sp3 hybridization in CH4?
In valence bond theory it is assumed the four electron pair bonds reside tetrahedrally about the carbon giving rise to the terahedral shape of the molecule. sp3 hybridisation is "necessary", it replaces the s , px, py and pz orbitals with four orbitals of identical energy (degenerate) with lobes pointing to corners of a tetrahedron- the 4 electrons are then promoted to these orbitals - the hybridisation energy. ...
What replaces oil once it is removed from the ground?
When oil is taken out of the ground in the oil fields, new oil replaces it. When an oil well no longer produces oil, water usually replaces the space. ...
