Oxygen atoms have a greater electronegativity than hydrogen atoms. Electronegativity is the ability of an atom in a molecule to attract electrons to itself.

What does bonds hydrogen and oxygen?
The sharing of electrons is what bonds hydrogen and oxygen together.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
What is the final acceptor of the electrons and hydrogen's of the electron transport chain?
oxygen
What is polarity in a water molecule?
The oxygen and hydrogen in water are bonded by a covalent bond. This means that the two lone lone electrons of hydrogen are shared with oxygen. Oxygen has a tendency to "hoard" electrons. So when it bonds with the hydrogen the two shared electrons are closer to the oxygen than to the hydrogen. As a result one side of water(the one with the oxygen) becomes slightly negative due to the fact that the oxygen has the two electrons closer to it. The side of the hydrogen becomes slightly positive as a result. When two or more molecules of water are placed together the slightly negatively charged oxygen from one molecule attracts the slightly positively charged hydrogen from another molecule forming a weak hydrogen bond. this hydrogen bond is formed as a result of the polarity of water.
Why are O2 bond broken by a hydrogen to form OH?
The hydrogen is attached directly to one of the most electronegative elements, causing the hydrogen to acquire a significant amount of positive charge.Each of the elements to which the hydrogen is attached is not only significantly negative, but also has at least one "active" lone pair.Lone pairs at the 2-level have the electrons contained in a relatively small volume of space which therefore has a high density of negative charge. Lone pairs at higher levels are more diffuse and not so attractive to positive things.and just for fun, here is another (equivalent) explanation: The normal result of O2 combining with H2 is water, H2O, not OH (although water can also be described as a combination of OH and H) but in any event, oxygen combines with hydrogen because oxygen has a stronger attraction for electrons (which is to say, a higher electronegativity) than hydrogen does, so if hydrogen and oxygen share electrons, with the electrons being unequally shared, spending more time with the oxygen than with the hydrogen, there is a net energy advantage (technically a heat of formation) which is greater than the energy of the oxygen and hydrogen by themselves.
In the compound H2O the electrons in the bonds are unequally shared between oxygen and hydrogen forming .?
polar bonds
What bond occurs when a pair of electrons is unequally shared between two atoms?
In H2O the electrons are shared by the oxygen atom and two hydrogen atoms. Although there are two hydrogen atoms, the electro-negativity (or ability to attract electrons) of the oxygen is greater than the hydrogens, therefore the electrons are pulled greater towards the oxygen resulting in the oxygen becoming "negatively charged" this results in the molecule becoming what is known as a "dipolar molecule". This is what causes water to be attracted to each other as each molecule has a positive and negative pole. Answered by Mason Rawling-Jones (currently 15).
What does bonds hydrogen and oxygen?
The sharing of electrons is what bonds hydrogen and oxygen together.
In the compound H2O the electrons in the bonds are unequally shared between oxygen and hydrogen forming what?
H2O, dihydrogen monoxide, is a compound formed by sharing electrons. Water, or H2O, is a polar covalent bond which means that is has an unequal sharing of electrons.
True or false Hydrogen and oxygen atoms have an equal number of electrons?
False, a Hydrogen has 1 electron and Oxygen has 8 electrons
What attractive force holds molecules of H2o together?
The attractive force is electrostatic, and described mathematically by Coulomb's Law. Because oxygen has a greater electronegativity than hydrogen, the electrons are shared unequally by these atoms, giving oxygen a negative charge and hydrogen a positive charge. And opposite charges attract.
How many electrons are in the outermost energy level of an oxygen atom as it shares electrons with hydrogen atoms as part of water molecule?
In water molecules there are 2 atoms of hydrogen of and 1 atom of oxygen present. each hydrogen atom shares 1 electron with the oxygen atom. So the total number of electrons shared with oxygen are 2,total no. of electrons shared by hydrogen is 2 and the total no. of electrons shared by each hydrogen atom is 1.
What do two atoms form when they do not share electrons equally?
When electrons are transferred rather than shared, the result is an ionic compound. If electrons are shared, the result is a covalent compound. This is true even when the sharing is unequal. In a water molecule, the electrons are shared unequally, since they are more attracted to the oxygen atom than they are to the hydrogen atoms, however, the result is still a covalent bond.
What are oxidation and reduction reactions?
Oxidation can be generally loss of hydrogen, addition of oxygen or loss of electrons. Reduction can be generally addition of hydrogen, loss of oxygen or addition of electrons.
Hydrogen and oxygen are what type of bonds?
Polar Covalent Bond. This is when a pair of electrons is shared between two atoms in a molecule but the electrons are not equally shared. Because the Oxygen atom has a stronger pull on the electrons than the Hydrogen, the electrons will be more drawn to the Oxygen atom.
What is the final acceptor of the electrons and hydrogen's of the electron transport chain?
oxygen
Is reacting with oxygen a physical property of hydrogen?
Reactivity is a chemical property.
