How is the valence shell of hydrogen in hydrogen compounds different from the valence shell of other atoms when they form bonds?

The "valence shell" of hydrogen contains only one electron. (This configuration is indicated as 1s1). Therefore, when it looses that electron, it is only a lone proton. This is highly important in acid/base reactions.
Hydrogen, H, (and helium, He) does not follow the "octet rule" when forming bonds with other elements. Rather they both follow a special rule, sometimes called the "duet rule." While most elements want to have 8 valence electrons, H and He only want a total of 2.

Number of valence electrons in two hydrogen atoms?
Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two valence electrons :)
What parts of atoms combine to form different compounds with different properties?
I think electron cloudElectrons, especially the valence electrons (in the outmost orbitals), are involved in bonding atoms to other atoms to form new molecules of different compounds.
When nitrogen and hydrogen combine what will be the ratio of hydrogen atoms to nitrogen atoms in a molecule of the resulting compounds?
1to 3
Atoms and molecules of different elements can do what to form molecules of compounds?
(Two or more than two ) Atoms or molecules of different elements combine to form compounds, like: Hydrogen(atom) and Chlorine combine to form HCL (an acid) Hydrogen(molecule) and oxygen combine to fom H2O (water)
How many valence electrons does H2O2have?
H2O2 is a compound, and the concept of "valence electrons" applies to atoms but not to compounds. If the question is or should be intended to be, "How many valence electrons did the atoms in one formula unit of H2O2 have before they reacted to form the compound?", the answer is one from each hydrogen atoms and six from each oxygen atom, for a total of 14.

What is the compound that contains carbon and hydrogen atoms?
There are several billion different such hydrocarbon compounds.
how many hydrogen atoms must be bond to silicon to give it an octet of valence electrons?
Silicone has 4 valence electros so it would need 4 hydrogen atoms to give itself an octet of valence electrons.
Why does water and hydrogen peroxide have different properties?
They are totally different compounds, even though they both contain hydrogen and oxygen. The ratios of the elements are not the same. The formula for water is H2O, and for hydrogen peroxide is H2O2. In a molecule of water, two hydrogen atoms are chemically bonded to one oxygen atom, whereas in one molecule of hydrogen peroxide, there are two atoms of hydrogen and two atoms of oxygen bonded together. This makes them completely different compounds with different properties.
What are the differences in atoms in elements and compounds?
atoms in elements are one kind of atom where as atoms in compounds are different atoms example gold is a element and it is made up of only gold atoms and water is a compound and it is made up of hydrogen and oxygen atoms
What are valence atoms?
Valence atoms are actually electrons. These particular electrons are what helps form chemical bonds. They are free to attach to other atoms to form compounds and molecules.
What is the valence atoms of oxygen?
Oxygen has the valency of 2 in most of the compounds.
When nitrogen and hydrogen combine what will be the ratio of hydrogen atoms to nitrogen atoms in a molecule of the resulting compounds?

What is organic compounds in which there are twice as many hydrogen atoms as oxygen atoms?
water
How many compounds are in 3H2O?
3 Hydrogen atoms, 2 Oxygen atoms.
