Why does it take two atoms of Hydrogen to join one atom to make water?

In sodium oxide there are two sodium atoms for each oxygen, formula is Na2O. The reason is that oxygen has a valency of 2 and sodium has a valency of one. They form an ionic compound with two Na+ ions to each O2- . In both of these different sorts of ions the outer electron shell is the same as a noble gas--sodium loses one electron to get the outer shell configuration of Neon and oxygen gains two electrons to get the outer shell configuration of Neon .

∙ 13y agoA hydrogen atom needs to gain 1 electron to achieve a stable outer shell of 2 electrons. It gets. In covalent compounds like H2O it gets this by "sharing" electrons with another atom like oxygen.
Oxygen, needs to gain 2 electrons to achieve its own stable outer shell of 8 valence (outer shell) electrons. It gets this in the same way by "sharing" with another atoms such as hydrogen.
In a single bond like those in H20 each atom gives one electron to be "shared" between the two atoms.

∙ 11y agoWell, shells are materials that hold electrons in place, and the first shell can hold 2 electrons, and the next one can hold 8. Let me show you the reason:
1 molecule of oxygen contains 8 electrons, and 1x8=8.
So so far we have eight, with fills the first shell, but the second one is still one-quarter empty.
Now, one molecule of hydrogen has 1 electron, and 1x2=2.
And now, 2+8=10, which fills both shells, because:
The first shell can hold 2 electrons, and the second one can hold 8 electrons. Which equals to:
10!
And now that it is full, it creates a chemical reaction.

∙ 11y agoIn order for both hydrogen atoms and the oxygen atom to have a filled valence shell of electrons, they must form covalent bonds with one another. The oxygen atom forms a covalent bond with each of the hydrogen atoms. When combining with oxygen, each hydrogen atom has two valence electrons, and the oxygen atom has eight valence electrons. By having filled valence shells, the atoms become stable.

What are two of me in one water molecule?
Two hydrogen atoms. As H2, they join one oxygen atom to form H2O
What is the Lewis formula for C8H18?
Draw 8 carbon atoms in a row. And then join three hydrogen atoms to every carbon atom in the corners. Join two to the every other.
When two or more atoms chemically join they form?
Molecules are combinations of two or more atoms.
Why does water have strong hydrogen bonds?
The hydrogen atom of one water molecule, with its partial positive charge, is attracted to the oxygen atom of a neighboring water molecule, with its partial negative charge, forming a hydrogen bond.
Nuclear fusion different then when atoms join to form a molecule?
Nuclear fusion is when atom join to form another element or substance. Nuclear fission is when atoms split apart.
What atoms join together to make water?
Two atoms of hydrogen and one atom of oxygen.
What are two of me in one water molecule?
Two hydrogen atoms. As H2, they join one oxygen atom to form H2O
What is water molecules composed of?
There's a picture in the linked page showing a single water molecule, consisting of one oxygen atom (in red) and two hydrogen atoms (in white), hence, the formula for a single molecule of water, H2O.
How many hydrogen atoms are necessary to join with oxygen to make it a stable compound?
Two hydrogen atoms need to be combined with one oxygen atom to form a molecule of water (H2O). Or you could have two hydrogen to two oxygen atoms, forming hydrogen peroxide (H2O2) but this is unstable and decomposes back to water and oxygen gas.
Can a third hydrogen join a water molecule?
No. A third hydrogen atom can not join a water molecule. However, it can partially join a water molecule through a process called hydrogen bonding. So the third hydrogen is more attached to its own oxygen atom than it is attached to the other oxygen atom although it is attached to both.
Is this true when one burns hydrogen with oxygen to make water two oxygen atoms go into each water molecule?
No. When making water by burning Hydrogen in Oxygen (a very explosive reaction) is that 2 atoms of Hydrogen and 1 atom of Oxygen join together to form 1 water molecular - H2O.
What occurs during During The Dark Reactions Of Photosynthesis?
Hydrogen atoms released from water are added to carbon dioxide molecules so that carbon oxygen bonds are broken and carbon atoms can join together. Carbon dioxide consists of a carbon atom attached to two oxygen atoms. That way, a carbon atom joins two other carbon atoms. One of the hydrogen atoms joins the carbon atom and one of the hydrogen atoms joins with the oxygen atom. You end up with the carbon atom attached to four different atoms.
What is the Lewis formula for C8H18?
Draw 8 carbon atoms in a row. And then join three hydrogen atoms to every carbon atom in the corners. Join two to the every other.
Do hydrogen have atom?
Firstly, atom made up of nucleus and electrons. More atoms join up to make a molecule. Hydrogen is made up of bunch of molecules form by 2 Hydrogen atom join together. Basically, Hydrogen is the atom. If you are still unclear bout that, you might want to google it, shouldn't be hard to find. Good luck.
What is watering?
An engineered irrigation or watering system. As distinct from meteoric watering = natural watering.
What does 2H2O mean?
H2O is the molecular formula for water. H is the elemental symbol for hydrogen, sub fix regards two of its atoms present. Oxygen is represent by O. The numerical prefix of 2 regards a quantity of two water molecules.
Name the elements that are joined together to make water a compound?
It's H2O which means two hydrogen molecules to one oxygenThe elements of Hydrogen and oxygen are chemically joined together to form water. Two atoms of hydrogen and one atom of oxygen are joined together chemically to form one molecule of water.
