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


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.


Why does the oxygen atomhave more electrons surrounding it than a hydrogen atom?

A hydrogen only has one valence electron, while oxygen has 6.


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

Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell


What electrons are in oxygen valence?

An oxygen atom has two valence electrons.


How many total electrons did the oxygen atom have before it bonded covalently withthe hydrogen atoms to form a water molecule?

An unbonded oxygen atom has eight electrons, with six of the electrons located in the valence shell. Two of the valence electrons are unpaired, and therefore can undergo covalent bonding with other oxygen atoms or nonmetals (such as hydrogen).


How many valence electrons are in o?

O - Oxygen has 6 valence electrons.


Do all covalent bonds share electrons equally?

In a way. for example, h^2O(water), hydrogen has one valence elctron and oxygen has 6 valence electrons.Both Hydrogens are going to share their one valence electron to turn oxygen into a stable octet(basically let oxygen have 8 valence electrons). and yes they share electrons equally.


How many valance electrons does oxygen have?

Oxygen has 6 valence electrons. A person can determine the number of valence electrons by looking at the periodic table. since oxygen is in the 6th column form the left, it has 6 valence electrons.


How many atoms valence electrons are in an oxygen atom?

Oxygen has six valence electrons.


Valence electrons of oxygen?

Oxygen as 6 valence electrons.


How many valence electrons does a neutral oxygen atom have?

A neutral atom of oxygen would have 6 valence electrons.
