What element can act as both an electron donor and an electron acceptor?

Hydrogen, depending upon what element it is combining with, can act either as a metal or a nonmetal. But as a nonmetal it shares electrons in the form of covalent bonds, rather than actually donating them. Similarly, carbon can react with metals or nonmetals but forms covalent bonds. To truly donate or accept electrons is to form ionic bonds, and no element has the flexibility to form ionic bonds both as a donor and as an acceptor. Elements can do one or the other, if they form ionic bonds. Some elements only form covalent bonds.

What compounds can act as both an electron donor and electron acceptor?
The answer is acids.... "acids are most broadly defined as compounds that are electron pair acceptors."
What is the original molecule that is the electron donor for both photosystems?
water
How is the role of oxygen in cellular respiration similar to the role of NAD plus in fermentation?
As they both accept electrons and are reduced, but NAD carries stripped electrons from glucose ( becoming NADH ) to the electron transfer chain while oxygen is the final electron acceptor.
Does sodium have ten neutrons?
Actually, the element Sodium has eleven (11) electrons. You can tell by its Atomic number. (The number at the top left side of the element's box.)The Atomic number is both the element's proton and electron number.
What three things is each element composed of?
Protons, neutrons (both in the nucleus) and electrons.

What is the original molecule that is the electron donor for both?
water
What is the original molecule that is the electron donor for both photosystems?
water
What is a compensated semiconductor?
compensated semiconductor...SEMICONDUCTORS WHICH CONTAIN BOTH DONOR AND ACCEPTOR DOPANT ATOMS IN SAME REGION IS CALLED COMPENSATED SEMICONDUCTOR.
What is the intermediate electron acceptor for oxidations that occur in both glycolysis and in Krebs cycle reactions?
NADH ( Google that to get full name )

What is the net charge on a n-type or a p-type substance?
There is no net charge on either substance. However, an N type substrate contains atoms (such as arsenic or phosphorous) trapped in its lattice that have an electron (called a donor electron) in the outer (valence) band of electrons, which can be easily removed by a relatively weak electromotive force (voltage). A P type substrate, although electrically neutral, contains an element (such as boron) which has one fewer electrons in its valence band that it would like to have, making it an acceptor. The missing electron is often called a "hole". To elaborate slightly, bands of electrons like to have a certain number of electrons to be "stable". A donor atom may have one, or perhaps five, electrons in its valence band, while an acceptor might have three or seven. Both would be happier with zero or four or eight. When an N and a P type substance are in contact, a negative voltage on the N material with respect to the P material will allow electrons to move from the donor material to the vacant holes in the acceptor. If the voltage is applied in reverse, the negative charge on the P material attracts the holes away from the junction, and the (relatively) positive charge on the N material attracts electrons away from the junction, and very little current flows.
The general idea behind the electron transport chain?
That ADP is converted to ATP. That electrons are shuttled down the chain of electron acceptors, until molecular oxygen acts as the final exlecron acceptor.
Is distill water a acid or a base?
In general it is said to be neutral, but having said so you can (and Mr. Lewis did in his theory on acid and base) see water as both an acid and as base:Acid behaviour of H2O, donating a proton to base B- H2O + B- --> OH- + HB (1)base behaviour of H2O, accepting a proton from acid HB H2O + HB --> H3O+ + B- (2)Ampholyte*) behaviour: donating a proton to itself as acceptor(H2O)donor + (H2O)acceptor OH- + H3O+which makes water having both concentrations [H3O+] = [OH-] = 1.0*10-7, so: pH = 7*) Ampholyt means: both donor and acceptor, at the same time, 'like twins'
What is NAD and FAD?
NAD stands for nicotinamide adenine dinucleotide and FAD stands for flavin adenine dinucleotide. Both are electron carriers which have many roles to perform.
What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
What relationship do element drawings and electron dot diagrams share?
They both show the amount of electrons in the outer shell.
