Does oxidation gain or lose oxygen or hydrogen?
Oxidation typically involves the loss of electrons or the gain of oxygen atoms. Oxidation does not necessarily involve the gain or loss of hydrogen atoms; however, in some cases, oxidation reactions can involve the loss of hydrogen atoms.
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.
Why does oxygen have more electronegativity than hydrogen?
Oxygen has more electronegativity than hydrogen because it has more protons in its nucleus, which creates a stronger positive charge to attract electrons. Additionally, oxygen is smaller in size than hydrogen, which leads to stronger electron-nucleus attraction.
Which atom pulls the shared electrons more closely to itself in an O-H bond and why?
Oxygen is more electronegative than hydrogen, which means it will pull the shared electrons more closely to itself. Very few elements will lose electron density to hydrogen in common chemistry.
Is a oxygen and hydrogen atom a positive or negative charge?
An oxygen atom has a partial negative charge due to its higher electronegativity and tendency to attract electrons. A hydrogen atom has a partial positive charge in a molecule due to its lower electronegativity and tendency to lose electrons.
Does oxidation gain or lose oxygen or hydrogen?

What is the ratio of hydrogen to oxygen in a carbohydrates?
The ratio of hydrogen to oxygen in a monosaccharide is 2:1--the formula for any of the three is C6H12O6. Things get weird when you go into disaccharides and above--you lose two hydrogens to create a free bonding pair.
Is it possible 2 lose an atom sweating?
When people sweat, they lose water through their skin pores. For the fact that water consists of hydrogen and oxygen atoms, it is true that someone can lose an atom from sweating.

Does sulfur gain electrons when combining with other elements?
It can both gain and lose electrons depending on the different elements. With hydrogen, it gains electrons to produce hydrogen sulphide and it will lose electrons with oxygen to produce sulphur oxides. Generally it will tend to gain electrons as it is in group 16 of the elements and so is quite negatively electrovalent but against a more negatively electrovalent elements it can be forced to lose electrons unwillingly as in the case of oxygen. Even though oxygen is also in group 16, sulphur is an order below oxygen and therefore less negatively electrovalent that oxygen.
Why does oxygen have more electronegativity than hydrogen?
Oxygen has more electronegativity than hydrogen because it has more protons in its nucleus, which creates a stronger positive charge to attract electrons. Additionally, oxygen is smaller in size than hydrogen, which leads to stronger electron-nucleus attraction.
Do acids lose or gain hydrogen ions?
Acids lose hydrogen ions when they donate them in a chemical reaction, making them stronger acids.
How do you lose oxygen when your running?
You don't lose it, you use it. Oxygen is used to burn the hydrogen of sugar and fats to generate the high energy phosphate bonds (ATP) that your cells need to do work. It's also used to "burn" the carbon in the fats and sugars, but you get no energy from that, only heat.

An oxygen atom has a partial negative charge due to its higher electronegativity and tendency to attract electrons. A hydrogen atom has a partial positive charge in a molecule due to its lower electronegativity and tendency to lose electrons.
How does the light reaction of photosynthesis affect our supply of oxygen?
Well the light reactions produce oxygen gas which will affect our supply of oxygen gas.The oxygen gas is produced when the hydrogen atoms of the water molecules lose their electrons to photosystem 2 and the oxygen atom cannot exist on its own and must be diatomic in order to achieve octet configuration
How many electrons will hydrogen gain or lose when it forms an ion?
Hydrogen usually loses its single electron to become a hydrogen ion, H+.
