Whether or not hydrogen (or any atom or molecule) gives or receives electrons depends on the nature of the thing it is interacting with. If the other atom is more electronegative than hydrogen, it will take an electron from hydrogen. If hydrogen is the more electronegative species, hydrogen will take the electron. There are many reactions in which electrons are donated or received, and to understand them, you must look at the nature of the two species involved in the exchange. Primarily the answer will depend on the relative electronegativity of the two atoms (or for molecules, their relative nucleophilicity or electrophilicity). One way to think about it is like a game of tug-of-war. If two people pull in opposite directions on a piece of rope, whoever is stronger will pull the rope towards them. In the same way, whichever molecule "wants" the electron more will take it from the other. What makes a molecule or atom "want" an electron more than another is another topic...

Give an example of an atom that will give up its outermost electron?

Hydrogen is the best example that give up it outermost electricity easily. The reason for this is because hydrogen have weak electro negativity.


Why H3PO4 is reducing agent?

due to th H3PO$ has 3 ionization steps any step give hydrogen ion (H2PO4 + H and HPO4 + H)with one electron which compine with other hydrogen to give hydrogen gas and two electron which make redction reaction and soon


Why is a hydrogen nucleus charge?

A hydrogen nucleus has got just one electron, thereby meaning that it can either accept one more electron or give away its sole electron to attain the stable electronic configuration. However, it usually shows the non metallic behaviour of accepting an electron.


Does helium contain hydrogen?

No. Hydrogen and helium are separate elements. Elements do not contain other elements. But an element can give off or take electron from other elements.


Why are some elements are stable on their own while others are more stable in a compound?

its because some are naturally stable like helium, when some like hydrogen have an extra electron in their electron clouds. That's why they are unstable. When they meet with an element with one extra electron they can be stable because the first electron cloud holds 2 electrons. ex. : hydrogen - 1 electron hydrogen - 1 electron adding both together will give you a full eletron cloud. Hope this helps!


How does hydrogen and oxygen form water?

The oxygen atom requires 2 electrons to complete its valence (outer) shell. Hydrogen is special in that it can either give or take one electron and still be stable. So hydrogen gives its electron to oxygen, and two hydrogen fills up all of oxygen's valence shell, and it forms water.


Why does Oxygen and hydrogen combine?

This is due to the instability of oxygen and hydrogen atoms ..................... as oxygen needs two electrons while hydrogen has the ability to give electron , so therefore two hydrogen share there electrons with the oxygen atom , thus stabilizing it ...


Give the reasons for why the hydrogen is not found in free state?

it the smallest element with one valence electron and will bond to just about anything, theres no scenario in nature where hydrogen would not have another element around to bond to

Does hydrogen give up valence electrons eaisly?

Yes, it can stabilize by giving away its electron, the reactions between an acid and a metal can be explained by this behavior.


Why is deuterium considered a isotope?

From its proton and electron count, it is hydrogen. But an extra neutron present in the nucleus, means the atom is heavier, although chemically it is very similar to normal hydrogen. It is unusual to give an isotope a special name. You might call it Hydrogen-2.

Will a chlorine ion lose its extra electron to a sodium ion when they are separated by an electric field in an aqueous solution?

no, because the electric potential of sodium is so low.But chlorine will give electron to proton to form hydrogen gas


How many covalent bonds form from hydrogen and halogen?

1 bond. Hydrogen has 1 electron to share and the halogens have 7 ( 1 unpaired) so it will share it's one with hydrogen's one to give the halogen an octet.

Does heating matter affect the mass of an object?

Whether or not heating matter affects the mass of an object depends on how hot you make the object. Normal heating of matter has little effect on the mass of an object. However, if you heat a substance like hydrogen to the point where you strip off the electron, the electron and the proton have more mass than the hydrogen atom. Then when the proton and electron come together, they will give off heat. You can calculate the amount by looking up the mass of the electron and the proton and subtracting the weight of a hydrogen atom. The formula is e = Mc2


Why pure water is a bad conductor of electricity?

Water does not conduct electricity. It is the impurities (ions) that allow water to conduct electricityPure water is 'bad' conductor of electricity. As there are 'no' free electrons there to carry electricity forward. As hydrogen has 'shared' the only electron with oxygen atom, it has 'relative' positive charge. Hydrogen does not 'donate' electron to oxygen, though it 'demands' electron from hydrogen. Otherwise hydrogen will get 'net' positive charge. So water becomes one of the most polar molecule. And so it forms 'Hydrogen bond' with other molecules. Once you add salts like sodium and potassium chloride to it, which are fully ionized, it becomes very good conductor of electricity. Now question arises 'Why sodium and potassium get 100 % ionized'. For that you see the electronic configuration of them. Sodium has 2,8,1 and potassium has 2,8,8,1. Chlorine has 2,8,7. So sodium and potassium wants to 'give' extra electron to other atoms so that there 'octate' is full filled. By giving this 'extra electron', They both have 10 and 18 electron in hand. So 'net' loss of 'about' 10 % to 5 % electrical charge only respectively. Chlorine want extra electron to full fill outer orbit. For it, it is 'net' gain of 'about' 10 % electrical charge only. In case of hydrogen to give electron is 100 % loss or gain of electrical charge, so it has to thinks twice before giving or taking electron. So it 'shares' electron with other hydrogen atom. So both have 2 electrons in there outer orbit. It is the oxygen,chlorine atom whoforcibly try to take away electron from hydrogen atom to complete there 'octate'.


What two electron carrier molecules feed electrons into the electron transport chain?

NADH and FADH give high energy e- to the ETC which produces a high concentration gradient of hydrogen ions which then feed down into ATP synthase. The energy of the hydrogen ions moving down the ATP synthase generates the production of 36ATP in the mitochondria cristae.


Why is oxygen gas produced from the decomposition of H2O2 and not hydrogen gas?

Hydrogen has a much lower attraction for electrons than oxygen does (or in more technical terms, oxygen has a much higher electronegativity). So when hydrogen gives up an electron to oxygen, it creates a strong chemical bond (although not an ionic bond; hydrogen's electronegativity is too high for that). When hydrogen peroxide gives up excess oxygen, the hydrogen remains bonded to the remaining oxygen (since hydrogen peroxide becomes water, H2O). If instead the hydrogen peroxide were to give up hydrogen, you would lose the powerful bond between hydrogen and oxygen, and all you would get in exchange would be a much weaker bond between hydrogen atoms and other hydrogen atoms, in the diatomic hydrogen molecule. Chemical reactions move in the direction of the strongest available bonds.
