When oxygen and hydrogen combine to form water (H2O), oxygen contributes 6 valence electrons (group 16, 6 electrons) and each hydrogen atom contributes 1 valence electron (group 1, 1 electron), resulting in a total of 8 valence electrons in the water molecule.

How many pairs of valence electrons are there on the oxygen atom in the water molecule?

There are 4 valence electrons on the oxygen atom in the water molecule. Oxygen has 6 valence electrons, and in a water molecule, oxygen forms 2 covalent bonds with the hydrogen atoms, sharing 2 of its valence electrons with each hydrogen atom.


What is the valance electrons for H3O?

The H3O+ ion has three hydrogen atoms bonded to an oxygen atom. Each hydrogen atom contributes 1 valence electron, while the oxygen atom contributes 6 valence electrons. Therefore, the total number of valence electrons in the H3O+ ion is 3 (hydrogen) + 6 (oxygen) = 9 electrons.


What is the formula is the formula of hydrogen and oxygen?

Hydrogen contains one valence electron (one electron in its outer orbit) and oxygen contains six valence electrons, to become stable a element wants to have 8 electrons in its outer orbit. Therefore when hydrogen and oxygen combine, it will take 2 parts hydrogen and one part oxygen H2O


How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?

What determines chemical bonding in an element?

Atoms hold their electrons in valence shells, but each shell only holds so many electrons. If an atom's outer valence shell is full, it's inert (does not form bonds). If it's outer shell isn't full, then it will form bonds.


What is the number of valence electrons in CH2O?
