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 else can I help you with?
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."
Is tin an electron donor or an electron taker?
Tin can act as both an electron donor and an electron acceptor, depending on the chemical reaction it is involved in. In some reactions, tin can donate electrons to other elements, while in others, it can accept electrons.
What element must be present for both steps of cellular respiration to occur?
Oxygen is the element that must be present for both steps of cellular respiration to occur. It acts as the final electron acceptor in the electron transport chain, allowing for the production of ATP through oxidative phosphorylation.
What is the original molecule that is the electron donor for both photosystems?
water
Which element can form both positive and negative ions?
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.

What is a compensated semiconductor?
compensated semiconductor...SEMICONDUCTORS WHICH CONTAIN BOTH DONOR AND ACCEPTOR DOPANT ATOMS IN SAME REGION IS CALLED COMPENSATED SEMICONDUCTOR.
Which process is called as- Energy releasing metabolic process in which substrate is oxidised without an external electron acceptor?
Fermentation is the process where energy is released by the oxidation of a substrate without the involvement of an external electron acceptor. It allows cells to generate energy in the absence of oxygen by using organic molecules as both electron donors and acceptors.
What is the intermediate electron acceptor for oxidations that occur in both glycolysis and in Krebs cycle reactions?
The intermediate electron acceptor for oxidations in both glycolysis and the Krebs cycle is NAD+ (nicotinamide adenine dinucleotide). NAD+ accepts electrons and becomes reduced to NADH during these metabolic pathways. NADH can then donate its electrons to the electron transport chain for further energy production.
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.
Which element can form both positive and negative ions?
Hydrogen is the element that can form both positive (H+) and negative (H-) ions. When hydrogen gains an electron, it forms a negative ion, and when it loses an electron, it forms a positive ion.
Which of these elements has the same number of electron orbitals as the element sodium?
The element magnesium has the same number of electron orbitals as sodium - both have three electron orbitals. Sodium and magnesium are in the same period on the periodic table, which means they have the same number of electron shells.
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'
